Terms of Service

These Terms of Service ("Terms") govern your access to and use of Seonio at seonio.com, including the website, web application, accounts, reports, API, API keys, API documentation, software, content, educational materials, and tools (collectively, the "Service").

By creating an account, subscribing to a plan, purchasing Extra Usage, generating reports, using an API key, or otherwise using the Service, you agree to these Terms. If you do not agree, you must not use the Service.

If you use the Service on behalf of a company or other legal entity, you represent that you are authorized to bind that entity to these Terms. In that case, "you" refers to that entity.

The Service is intended to help users research, analyze, organize, and integrate SEO-related information. The Service and all outputs are provided for informational and analytical purposes only and do not constitute legal, financial, tax, marketing, compliance, or other professional advice.

3. Eligibility and accounts

3.1 Eligibility

You must have legal capacity to enter into a binding contract to use the Service. If you are below the age of majority in your jurisdiction, you may use the Service only with the consent of a parent or legal guardian and only where permitted by applicable law.

3.2 Registration

Anyone may register for an account. You agree to provide accurate, current, and complete information and to keep your account information up to date.

3.3 Account security

You are responsible for keeping your login credentials, API keys, and account access confidential. You are responsible for all activities under your account, including API requests made using your API keys. You must notify us promptly at [email protected] if you suspect unauthorized access, leaked API keys, or misuse.

3.4 Account misuse

You must not create multiple accounts to circumvent testing-balance, plan, balance, promotional, rate-limit, or other usage restrictions. We may suspend or terminate accounts associated with such behavior.

4. Usage balance and data actions

4.1 Testing, included usage, and Extra Usage

After account verification, eligible accounts receive a one-time $1 testing balance. It does not renew and may be used without a subscription while it remains.

Eligible subscriptions include a dollar-denominated amount at each subscription-month boundary: Starter receives $15, Pro $37.50, and Business $90. Unused included usage is replaced at the next boundary and does not roll over, including for yearly subscriptions.

Active subscribers may purchase and use Extra Usage in the amounts shown in the Service. Extra Usage purchased under the current terms is valid for one year. Balance added before this rule took effect keeps its no-expiry terms. Testing balance is applied first, then included usage, followed by Extra Usage expiring soonest.

4.2 Shared use and prices

Website tools, REST API endpoints, and MCP tools use the same account balance. Published action prices are shown in the Service or API documentation. Dataset requests from the first authenticated website visit to a page use their published prices. Returning to the same page, including filters, within seven days costs $0 for successful dataset requests from that page. Those $0 website requests may appear in Usage as Cached. This is a billing label, not a statement that results were reused from a provider cache or are stale. REST API and MCP requests remain charged at their published prices. Outside this website courtesy, a successfully delivered lookup may be charged even if the result is empty; failed requests are not intentionally charged.

4.3 Nature of the balance

The usage balance is a contractual right to use eligible Service features. It is not a bank account, deposit account, or stored-value payment instrument; is non-transferable; and is not redeemable for cash except where mandatory law requires otherwise.

4.4 Insufficient balance and no automatic overages

Paid data actions may be rejected when the available balance is insufficient. Unless we expressly offer and you enable a different arrangement, Seonio does not intentionally allow usage to create overage charges beyond the available balance.

4.5 Changes

We may change included amounts, action prices, included tools, and purchase options prospectively. Material adverse changes to paid entitlements will not retroactively reduce already-paid rights during the current billing period except where necessary for legal compliance, security, abuse prevention, or changes in third-party dependencies outside our reasonable control.

5. Subscription plans and free testing

5.1 Free testing balance

At the time of writing, verified accounts receive a one-time $1 testing balance. No payment method or subscription is required to receive or spend it. Creating an account normally does not open a payment checkout.

5.2 Subscription pricing

At the time of writing, Starter costs $15 per month or $120 per year, Pro costs $30 per month or $240 per year, and Business costs $60 per month or $480 per year. Subscriptions begin when payment is completed; no trial applies. Current pricing, billing intervals, taxes, included usage, and features are shown on the pricing page and at checkout.

5.3 Access

Testing and subscription access are subject to account verification, subscription status where applicable, available spendable balance, technical availability, product restrictions, and these Terms. Paying before email verification does not enable data actions until account verification is complete.

6. SEO API and MCP

6.1 Access and authentication

Seonio may provide REST API endpoints and MCP tools for SEO-related data. REST access requires an API key; MCP may use OAuth or a bearer API key. Both require an eligible account and use the shared usage balance.

6.2 Pricing and balance

REST and MCP action prices are shown in the API documentation. Charges use testing balance first; for active subscribers they then use included usage and Extra Usage. You are responsible for reviewing applicable prices before use. Continued use after prospective pricing information is updated constitutes acceptance for future requests.

6.3 Keys and security

You must keep API keys confidential and secure. You must not publish API keys in public repositories, client-side code, websites, mobile apps, logs, screenshots, publicly visible support tickets, or other publicly accessible locations.

We may revoke, rotate, suspend, or limit credentials where reasonably necessary for security, abuse prevention, suspected compromise, excessive errors, rate-limit violations, non-payment, legal compliance, or protection of the Service.

6.4 Rate limits and fair use

We may enforce rate limits and other fair-use controls. At the time of writing, the limit is 20 data requests per second per account across website, REST API, and MCP actions. Excess requests may be rejected, including with HTTP status code 429.

6.5 Errors, caching, and integrations

Responses may include errors for invalid credentials, ineligible accounts, insufficient balance, invalid input, rate limits, source unavailability, or third-party failures. You are responsible for appropriate retry logic, backoff, caching, monitoring, validation, error handling, and safeguards.

SEO data changes over time. You may cache successful API responses for lawful internal business purposes or to operate your product unless the Service, documentation, or applicable law states otherwise. You are solely responsible for products, scripts, workflows, and integrations you build using Seonio outputs.

7. Billing, payments, and cancellation

7.1 Billing

Starter, Pro, and Business are billed in advance on a recurring monthly or yearly basis. Extra Usage purchases are billed at the time of purchase unless stated otherwise.

7.2 Automatic renewal

Unless cancelled, subscriptions renew automatically at the end of each billing period. Extra Usage purchases are one-time purchases.

7.3 Payment processor

Payments are processed by Stripe or another designated payment provider. By purchasing a subscription, Extra Usage, or another paid feature, you authorize us and our payment processors to charge the applicable fees, taxes, and valid adjustments to your selected payment method.

7.4 Taxes and VAT

Prices, currency, and whether taxes are included or added will be shown at checkout.

Where applicable, VAT or other indirect taxes may be charged based on your location, status as a business or consumer, and applicable tax law.

If you are a business customer in the EU and provide a valid VAT ID, the reverse charge mechanism may apply where legally available.

You are responsible for any taxes that apply to your purchase, except taxes based on our net income.

7.5 Failed payments

If a payment fails, is reversed, or is subject to a chargeback, we may suspend or limit access to paid features, the usage balance, credentials, or the account until the issue is resolved.

7.6 Cancellation

You may cancel a subscription at any time through your account settings. Cancellation stops future renewals. Unless mandatory law requires otherwise, cancellation does not retroactively cancel charges already incurred for the current billing period or completed Extra Usage purchases.

7.7 Effect of cancellation

If you cancel, you keep subscription access until the end of the current paid period. Included usage expires with entitlement; unexpired purchased Extra Usage remains on the account until its stated expiry but cannot be spent without an active subscription. Any remaining testing balance stays usable. Earlier balance that retains no-expiry terms remains on the account under those terms.

Cancellation does not automatically delete your account.

8. Commercial refund policy

This section describes our commercial refund policy and does not limit any mandatory statutory rights you may have as a consumer.

8.1 First purchase refund window

For first-time paid purchases, you may request a full refund within 7 days of the initial purchase.

8.2 Significant usage

This commercial refund policy does not apply where account activity shows significant usage beyond normal testing or evaluation. We will assess this in good faith based on actual use of the Service, including reports, REST and MCP actions, balance consumption, and other account activity.

8.3 Extra Usage refunds

Extra Usage purchases are generally non-refundable after any purchased balance has been used, unless required by law or unless we expressly state otherwise. Where a refund is approved, we may deduct the value already consumed.

8.4 Later refunds

After the initial 7-day refund-request period, subscription fees, Extra Usage purchases, and other paid features are generally non-refundable unless required by law or unless we expressly state otherwise.

8.5 How to request a refund

Refund requests should be sent to [email protected] and should include the account email address used for the purchase.

9. Consumer right of withdrawal (EU consumers — Widerrufsrecht)

If you are a consumer in the European Union, you have a statutory right to withdraw from a distance contract within 14 days without giving any reason.

9.1 Withdrawal period

The withdrawal period is 14 days from the day the contract is concluded, such as the day you subscribe or purchase Extra Usage.

9.2 Exercise of the right

To exercise your right of withdrawal, you must inform us by an unequivocal statement, such as by email or letter, that you wish to withdraw. It is sufficient to send this communication before the withdrawal period expires.

Contact for withdrawal:

Foundea GmbH
Seonio.com
Lise-Meitner-Str. 9
89081 Ulm
Germany
Email: [email protected]

You may use the Model Withdrawal Form at the end of these Terms, but this is not mandatory.

9.3 Effects of withdrawal

If you validly withdraw, we will reimburse payments received from you without undue delay and no later than 14 days after we receive your withdrawal notice, using the same payment method unless expressly agreed otherwise.

9.4 Immediate performance during the withdrawal period

If you request that we begin providing the Service before the 14-day withdrawal period ends, including by using paid features, spending included or Extra Usage, or making data requests, you expressly request immediate performance.

If you then exercise your right of withdrawal, we may charge you an amount proportionate to the services already provided up to the time we receive your withdrawal notice, to the extent permitted by applicable law.

Where applicable law provides that the right of withdrawal expires after full performance following your express request and acknowledgment, that rule applies.

10. Nature of SEO data and no performance guarantees

SEO data is dynamic, estimated, and often dependent on third-party sources, public web data, search engines, website availability, platform restrictions, and changing algorithms.

You acknowledge that:

reports, estimates, API responses, traffic data, backlink data, rankings, keyword data, clustering results, transcripts, authority metrics, SERP data, and other outputs may be incomplete, delayed, approximate, unavailable, or inaccurate
we do not guarantee any ranking, traffic, indexing, backlink, business, advertising, revenue, or marketing result
the Service may rely on third-party sources that can change without notice
API fields, metrics, coverage, and response shapes may change over time
you are responsible for verifying outputs before relying on them for business, legal, compliance, publication, product, or customer-facing purposes

The SEO wiki and any educational content are provided for general informational purposes only.

11. User inputs and your responsibilities

You may submit keywords, domains, URLs, search queries, project data, API request bodies, and other inputs to the Service ("Inputs").

You represent and warrant that:

you have the right to submit the Inputs
your Inputs and your use of the Service do not violate any law, regulation, contract, intellectual property right, privacy right, publicity right, database right, or other third-party right
you will not use the Service to process, scrape, extract, monitor, enrich, profile, or publish data in a way that is unlawful in your jurisdiction or in the applicable jurisdiction of the target website, platform, content source, or data subject
you will provide any legally required notices, consents, lawful bases, and safeguards for your use of Inputs and outputs

You remain responsible for your Inputs and for your decisions, products, publications, integrations, and actions based on the outputs of the Service.

12. License to process inputs

As between you and us, you retain your rights in your Inputs.

You grant us a non-exclusive, worldwide, royalty-free license to host, copy, process, transmit, store, and use your Inputs solely to:

provide and operate the Service
authenticate, process, and respond to API requests
generate reports, responses, and outputs for you
maintain security, prevent abuse, enforce limits, and troubleshoot issues
provide support
comply with legal obligations
improve the Service using aggregated or de-identified information

We do not use your Inputs to train AI models or sell them to third parties.

This license ends when your Inputs are deleted from our systems, except to the extent retention is required for legal obligations, recordkeeping, backup, security, fraud prevention, abuse prevention, or dispute resolution.

13. Permitted use of reports, API responses, and outputs

Subject to these Terms, you may use reports, API responses, and outputs generated through your account for:

your internal business purposes
your own websites, products, applications, and projects
client work performed by you or your organization
integrations that use Seonio data as part of a broader product or workflow, provided that you comply with these Terms and applicable law

You may share reports and outputs with your employees, contractors, and clients in connection with legitimate work, provided that you remain responsible for compliance with these Terms.

You must not:

resell standalone access to Seonio
resell or sublicense API access, API keys, or your account
resell raw datasets, raw API responses, or raw outputs as a separate data product
use the Service or outputs to build a substantially similar competing service without our written permission
misrepresent Seonio outputs as official, guaranteed, real-time, or independently verified data

14. Acceptable use

You must not, and must not allow others to:

use the Service in violation of any law or regulation
infringe or misappropriate intellectual property, privacy, publicity, database, trade secret, confidentiality, or other rights
use the Service to collect, scrape, store, publish, profile, or exploit data unlawfully
scrape personal data, confidential information, or protected content in a way that violates applicable law, including GDPR

attempt unauthorized access to the Service, API, infrastructure, accounts, API keys, or data
introduce malware, malicious code, harmful content, or abusive traffic

share, sell, lease, expose, or publish API keys

spam, phish, impersonate others, or engage in fraudulent or deceptive activity

We may investigate violations and suspend, limit, or terminate accounts, subscriptions, credentials, or usage balances where reasonably necessary.

15. Third-party services and sources

The Service may interact with or depend on third-party services, websites, search engines, hosting providers, payment processors, data providers, public sources, or platform content, including Stripe and publicly accessible web pages or video platforms.

We are not responsible for:

third-party services or websites
changes in third-party APIs, site structures, access restrictions, rate limits, pricing, or platform policies
the availability, legality, accuracy, completeness, or timeliness of third-party data
losses caused by third-party downtime, removals, blocks, policy changes, source changes, anti-bot measures, or data-provider changes

Third-party names, marks, and brands remain the property of their respective owners. Unless expressly stated, Seonio is not affiliated with, endorsed by, or sponsored by those parties.

16. Intellectual property

The Service, including its software, design, user interface, branding, databases, documentation, API documentation, API design, dashboards, reports, and SEO wiki content, is owned by us and/or our licensors and is protected by intellectual property and unfair competition laws.

Except for the limited rights expressly granted in these Terms, no rights are transferred to you.

We grant you a limited, non-exclusive, non-transferable, revocable right to access and use the Service during a valid entitlement with available usage balance, solely in accordance with these Terms.

17. Availability, maintenance, and changes to the Service

We aim to keep the Service available, but we do not guarantee uninterrupted or error-free operation.

The Service may be unavailable from time to time due to:

maintenance
updates
security work
internet outages
third-party outages
source-site blocking or technical restrictions
API rate limiting or capacity management
payment processor issues
events outside our reasonable control

We may modify, replace, suspend, or discontinue features, tools, API endpoints, data fields, pricing models, limits, or products where reasonably necessary for business, technical, legal, commercial, operational, or security reasons.

If a material change adversely affects a paid subscription, we will provide reasonable prior notice where practicable. For API changes, we will aim to provide notice where practicable, but urgent changes may be required for security, third-party dependency, abuse-prevention, compliance, or operational reasons.

18. Suspension and termination

18.1 By you

You may stop using the Service at any time. You may cancel your subscription through your account settings.

18.2 By us for cause

We may suspend or terminate your access, account, subscription, credentials, or usage balance if:

you materially breach these Terms
you fail to pay fees when due
your payment is reversed, disputed, or subject to chargeback
your use creates security, legal, fraud, abuse, technical, or operational risks
your API key appears compromised or publicly exposed
you exceed or attempt to evade rate limits, pricing, or usage controls
we are required to do so by law, court order, or binding governmental request
your use may expose us, other users, or third parties to harm or liability

Where appropriate, we may first give you a reasonable opportunity to remedy the issue.

18.3 Discontinuation

We may discontinue the Service or end accounts for business reasons on reasonable notice. If we do so without cause during a prepaid paid subscription term, we will refund the unused pro-rata portion of prepaid subscription fees for the remaining paid period.

For unused purchased Extra Usage, we will handle any refund, continued access, or migration in accordance with applicable law and any notice we provide at the time of discontinuation.

18.4 Effect of termination

Upon termination:

your right to use the Service ends
unused included usage is forfeited except where required by law
access to paid features ends immediately or at the end of the paid period, as applicable
API keys may be disabled
reports, API logs, account data, and other data may become inaccessible or may be deleted after a reasonable retention period, subject to legal obligations and our Privacy Policy
sections that by their nature should survive will survive, including payment obligations, intellectual property, permitted-use restrictions, disclaimers, liability provisions, governing law, and dispute provisions

19. Privacy and data protection

Our handling of personal data is governed by our Privacy Policy at https://seonio.com/privacy.

You are responsible for ensuring that your submission of Inputs, API request data, cached data, integrations, and use of outputs comply with applicable data protection, confidentiality, copyright, database, and platform rules.

If you submit personal data to the Service, you represent that you have an appropriate legal basis to do so.

For business customers where we process personal data on their behalf, our Data Processing Agreement (DPA) applies and is available on request.

20. Liability

20.1 Mandatory liability — unaffected

Nothing in these Terms excludes or limits liability for:

intent (Vorsatz)
gross negligence (grobe Fahrlässigkeit)
injury to life, body, or health
fraudulent concealment of a defect
an expressly assumed guarantee (Garantie)
claims under the German Product Liability Act (Produkthaftungsgesetz)
any liability that cannot be excluded or limited under applicable law

20.2 Slight negligence

In cases of slight negligence (einfache Fahrlässigkeit), we are liable only for breach of an essential contractual obligation (Kardinalpflicht) — meaning an obligation whose fulfillment is essential to the proper performance of the contract and on which you may regularly rely. In that case, liability is limited to the foreseeable damage typical for the contract.

20.3 Liability cap for business users

If you are using the Service in the course of a business, our liability for slight negligence under Section 20.2 is additionally limited to the fees paid by you in the 12 months preceding the event giving rise to the claim.

20.4 Third-party dependencies and SEO outputs

Subject to Section 20.1, we are not liable for losses caused solely by third-party source changes, third-party blocks, external platform outages, source data inaccuracies, API changes, rate limits, or your reliance on estimated SEO data, API responses, or outputs without appropriate verification.

21. Changes to these Terms

We may update these Terms for legal, regulatory, technical, security, operational, product, API, pricing, or commercial reasons.

If we make material changes, we will provide notice by posting the updated Terms on the website, in the Service, or by email where appropriate.

Unless mandatory law requires a different approach:

changes apply from the stated effective date
continued use of the Service after that date constitutes acceptance of the updated Terms
if you do not agree, you must stop using the Service and cancel your subscription before the updated Terms take effect

For material changes that negatively affect a paid subscription, we will aim to give reasonable prior notice, usually at least 30 days where practicable. API-related changes may require shorter notice where necessary for security, third-party dependency, abuse prevention, legal compliance, or operational continuity.

22. Consumer dispute resolution

We are not obliged and not willing to participate in dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle) pursuant to § 36 VSBG.

We encourage you to contact us directly at [email protected] first and will try to resolve complaints directly.

23. Governing law and jurisdiction

These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law rules and excluding the UN Convention on Contracts for the International Sale of Goods (CISG), to the extent applicable.

If you are a consumer residing in the EU or EEA, this choice of law does not deprive you of mandatory consumer protection rights granted by the law of your country of residence.

If you are a merchant, legal entity under public law, or special fund under public law, the exclusive place of jurisdiction for all disputes arising out of or in connection with these Terms is Ulm, Germany, to the extent permitted by law.

For consumers, statutory jurisdiction rules remain unaffected.

24. Miscellaneous

24.1 Entire agreement

These Terms, together with the Privacy Policy, DPA where applicable, and any policies expressly incorporated by reference, constitute the entire agreement between you and us regarding the Service.

24.2 Severability

If any provision of these Terms is invalid or unenforceable, the remaining provisions remain unaffected.

24.3 No waiver

Our failure to enforce any provision does not constitute a waiver of that provision.

24.4 Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign these Terms to an affiliate or in connection with a merger, acquisition, corporate reorganization, or sale of assets, provided this does not reduce your mandatory legal rights.

24.5 Force majeure

We are not liable for any failure or delay in performance resulting from causes beyond our reasonable control, including acts of God, natural disasters, war, government action, internet or infrastructure outages, third-party service failures, data-provider failures, payment processor failures, or source-site blocking.

24.6 Language

These Terms are written in English. In the event of any conflict between the English version and a translated version, the English version prevails to the extent permitted by applicable law.
