S A P O Terms of Use

Effective Date: 2026-05-20 Version: v2.0

These Terms of Use (Terms) are a legally binding agreement between you and Happ Technologies Inc., a Delaware C corporation (Happ Technologies, S A P O, SAPO, we, us, or our) governing your use of the S A P O mobile app, backend services, APIs, subscriptions, translation features, respelling features, and related websites or support channels (together, the Service).

By installing, accessing, or using S A P O, you agree to these Terms and to the S A P O Privacy Policy. If you do not agree, do not use S A P O.

1. Who May Use S A P O

You may use S A P O only if you can lawfully enter into these Terms and lawfully use the Service in your location.

S A P O is not directed to children under 13 and is not intended for anyone below the age where parental consent is required in their location. If you are under 18, you may use S A P O only with permission from a parent or legal guardian.

You may not use S A P O if you are barred from doing so under applicable law, sanctions, export controls, or app store rules.

2. What S A P O Does

S A P O provides text translation and respelling services. You enter text, choose supported source and target language options, and S A P O returns generated output.

S A P O uses backend services and server-side AI model provider(s) to generate results. Those providers may change over time. S A P O is not a professional advice service, emergency service, legal service, medical service, financial service, or safety-critical system.

S A P O may change, improve, limit, suspend, or discontinue features, supported languages, plans, limits, or availability, subject to applicable law and app store rules.

3. Accounts And Sign-In

S A P O may create an anonymous session so you can use basic app functionality. Some features, including subscription purchase, purchase restore, subscription management, and account deletion, require an authenticated account.

You may sign in with supported providers such as Google or Apple. You agree to provide accurate information where required, keep your account secure, and not share your account or use another person's account without permission.

You are responsible for activity under your account except where we are at fault. If you believe your account has been compromised, contact support@sapo.surf promptly.

4. Subscriptions, Billing, And Limits

S A P O offers a paid Polyglot subscription through supported subscription providers, such as Apple App Store or Google Play, with RevenueCat used for subscription management.

Payments, billing, subscription purchases, renewals, cancellations, taxes, refunds, and payment credentials are handled by the subscription provider, not directly by S A P O. Their terms and privacy policies apply to those payment and billing activities. S A P O receives limited subscription metadata needed to provide and manage your entitlement.

Unless the app store purchase screen states otherwise, paid subscriptions renew automatically for the period shown before purchase and continue until canceled. Your subscription provider may charge your account within 24 hours before the end of the current billing period. You can manage or cancel your subscription through the subscription provider, such as Apple through Apple account settings or Google through Google Play settings.

Deleting the app or deleting your S A P O account does not delete, manage, or cancel an active subscription. You must cancel or manage subscriptions through the subscription provider. Refunds, credits, and billing disputes are handled by the subscription provider unless applicable law or app store rules require otherwise.

At launch, current default limits are:

Limits are measured in input characters, not output characters or AI tokens. Unused monthly quota does not roll over unless S A P O states otherwise. We may apply technical limits, rate limits, abuse-prevention limits, and fair-use controls. The current app, app store purchase screen, and backend entitlement records control the plan, price, billing period, and limits available to you at the time of use.

A store subscription may be linked to only one S A P O account at a time. If your subscription is already linked to another S A P O account, you may need to sign in to that account, restore purchases there, or contact support.

5. Account Deletion

Authenticated users can request account deletion in the app through Settings > Data controls > Delete account. S A P O sends a verification email before deleting the account.

To complete account deletion, you must open the email deletion link on the device where S A P O is installed and where you are signed in to the S A P O account that requested deletion. If you open the link on another device, in a browser, while signed out, or while signed in to a different account, deletion may not complete.

Deleting your S A P O account does not delete or cancel an active subscription. You must manage or cancel subscriptions through the subscription provider, such as Apple through Apple account settings or Google through Google Play settings.

Account deletion may take time because S A P O must confirm authentication deletion, stop in-flight work, process retries, and coordinate with service providers. We may preserve limited records where necessary for subscription integrity, fraud prevention, legal compliance, dispute resolution, security, or deletion retry/recovery, as explained in the Privacy Policy.

6. Your Content And Privacy

Your Content means text or other material you submit to S A P O for translation or respelling.

You retain your rights in Your Content. You grant S A P O and our service providers a limited, worldwide, non-exclusive, royalty-free license to receive, transmit, process, transform, display, and return Your Content only as needed to operate, secure, troubleshoot, and improve the Service and as described in the Privacy Policy.

Do not submit content unless you have the right to do so. Do not submit passwords, payment card details, government IDs, health information, children's data, confidential business information, or other sensitive information unless you are legally allowed to do so and understand that S A P O and its service providers must process it to provide the requested feature.

The Privacy Policy explains how S A P O collects, uses, shares, stores, and deletes personal data. If these Terms conflict with the Privacy Policy about privacy or data protection, the Privacy Policy and applicable law control for that issue.

7. Open Phonetic Database

A portion of S A P O's revenue will be used to develop an open phonetic database containing mappings of phonetic respellings from every language to every language. The dataset will be developed by S A P O.

This does not give you ownership, governance, revenue, or approval rights in the database, S A P O, Happ Technologies, or any related intellectual property. S A P O may decide the development schedule, technical structure, release process, and open license or access terms for the database.

Unless S A P O provides a separate contribution feature, obtains required consent, or uses data that has been de-identified or aggregated so it no longer identifies you, text you submit in the app is not treated as a public database contribution.

8. Acceptable Use

You agree not to use S A P O to:

• Violate any law, regulation, sanctions rule, export control, court order, or third-party right.
• Submit content that is illegal, abusive, threatening, defamatory, hateful, exploitative, or harmful.
• Infringe or misappropriate intellectual property, privacy, publicity, or other rights.
• Submit content you do not have the right to submit.
• Use S A P O as a sole or primary source for medical, legal, financial, tax, emergency, safety-critical, or other professional decisions.
• Probe, scan, test, bypass, or undermine the security or access controls of S A P O without written permission.
• Abuse, overload, scrape, crawl, automate, resell, or commercially exploit the Service except as expressly allowed by us.
• Bypass, manipulate, or evade quotas, rate limits, subscription checks, purchase validation, or account restrictions.
• Reverse engineer, extract, or attempt to obtain model weights, prompts, proprietary systems, credentials, or non-public source material except where applicable law expressly allows.
• Use S A P O to build a competing service in a way that violates these Terms or applicable law.

We may suspend, limit, or terminate access if we reasonably believe you violated these Terms, created security or legal risk, abused subscriptions or refunds, or if we are required to do so by law, app store rules, or a service provider.

9. AI Output

S A P O output may be inaccurate, incomplete, offensive, unexpected, or unsuitable for your purpose. You are responsible for reviewing and deciding how to use output.

S A P O does not provide professional advice and does not guarantee that output is correct, unique, lawful to use in every context, or free from third-party rights. Do not rely on S A P O output for legal, medical, financial, emergency, safety-critical, or other high-risk decisions.

As between you and S A P O, and subject to these Terms, you may use output returned to you by the Service. You are responsible for ensuring that your use of output complies with applicable law and third-party rights.

10. Intellectual Property And Open Source

Except for Your Content and third-party materials, Happ Technologies and its licensors own all rights, title, and interest in S A P O, including the app, backend services, designs, logos, trademarks, software, documentation, and related technology.

S A P O, SAPO, associated logos, and related brand elements are trademarks or trade dress of Happ Technologies or its affiliates. You may not use our names, logos, or marks in a way that suggests endorsement, sponsorship, or affiliation without our prior written consent.

Certain S A P O source code may be made available under open-source licenses, such as the license published in the applicable repository. Those licenses govern your use of that source code. These Terms govern your use of the deployed Service, accounts, subscriptions, backend services, and hosted functionality. If an open-source license conflicts with these Terms for the licensed source code itself, the open-source license controls for that source code.

11. Third-Party Services

S A P O relies on third-party services, including app stores, sign-in providers, subscription providers, RevenueCat, backend and infrastructure providers, email providers, and server-side AI model provider(s). Third-party services have their own terms, privacy policies, availability, security, and data practices.

We are not responsible for third-party services except to the extent required by law. You should review the terms and privacy policies of any third-party service you use in connection with S A P O.

12. Apple App Store Terms

If you download or use S A P O through the Apple App Store, this section applies.

These Terms are between you and Happ Technologies, not Apple. Apple is not responsible for S A P O or its content, and Apple has no obligation to provide maintenance or support for S A P O. To the extent any warranty applies and S A P O fails to conform to that warranty, you may notify Apple and Apple may refund the purchase price, if any, as required by App Store rules; to the maximum extent permitted by law, Apple has no other warranty obligation for S A P O.

Apple is not responsible for claims relating to S A P O or your use of S A P O, including product liability claims, regulatory claims, consumer protection claims, or intellectual property claims. Apple and Apple's subsidiaries are third-party beneficiaries of these Terms for App Store-distributed copies and may enforce these Terms against you as a third-party beneficiary.

You represent that you are not located in a country subject to a U.S. government embargo or designated as a terrorist-supporting country, and that you are not listed on any U.S. government restricted-party list.

13. Termination

You may stop using S A P O at any time. You may also request account deletion as described in the Privacy Policy and these Terms.

We may suspend, terminate, or limit the Service or your access to it if you breach these Terms, create risk, misuse subscriptions or refunds, violate law, or if continued operation is no longer commercially, technically, legally, or operationally reasonable.

Termination does not affect rights or obligations that accrued before termination or that by their nature should survive, including intellectual property, payment, disclaimers, limitation of liability, dispute, and account deletion provisions.

14. Disclaimers And Limitation Of Liability

To the maximum extent permitted by law, S A P O is provided as is and as available, without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, availability, accuracy, reliability, or security.

To the maximum extent permitted by law, Happ Technologies Inc. and its officers, directors, employees, contractors, affiliates, licensors, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost goodwill, lost data, business interruption, or substitute services, arising out of or relating to S A P O or these Terms.

To the maximum extent permitted by law, our total aggregate liability for all claims arising out of or relating to S A P O or these Terms will be limited to the amount you paid to access S A P O during the three months immediately before the event giving rise to the claim.

Nothing in these Terms limits liability that cannot legally be limited or excluded, and nothing overrides mandatory consumer rights in your country of residence.

15. Changes To These Terms Or The Service

We may update these Terms from time to time, including when we change features, providers, subscriptions, limits, legal requirements, or app store rules. When we make material changes, we will update the Effective Date and provide notice where required by law or app store rules.

If you continue using S A P O after updated Terms take effect, you agree to the updated Terms to the extent permitted by law.

16. Governing Law And Disputes

These Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-law rules, except where the laws of your country of residence require a different choice of law for consumer protection reasons.

Before filing a claim, you agree to contact support@sapo.surf and try to resolve the dispute informally. If informal resolution is not possible, claims may be brought in courts with jurisdiction over your place of residence where required by mandatory consumer protection law, or otherwise in the state or federal courts located in Delaware, USA.

To the fullest extent permitted by law, disputes must be resolved on an individual basis only. You and we waive any right to participate as a plaintiff or class member in any class, collective, consolidated, or representative proceeding. If this waiver is not enforceable for a particular claim, it does not apply to that claim.

17. Other Terms

• Entire agreement. These Terms and the Privacy Policy form the entire agreement between you and Happ Technologies about the Service, except for any open-source license that applies to source code.
• Severability. If any part of these Terms is invalid or unenforceable, the rest remains in effect.
• No waiver. Our failure to enforce a provision is not a waiver of our right to enforce it later.
• Assignment. You may not transfer these Terms without our prior written consent. We may transfer these Terms in connection with a merger, acquisition, financing, reorganization, sale of assets, or similar transaction, subject to applicable law.
• No third-party beneficiaries. Except for Apple as described above, these Terms do not create third-party beneficiary rights unless they expressly say otherwise.
