Terms Of Use

Aug 11, 20268 min read#stikoo#TermsOfUse

Welcome to Stikoo (the "App"), provided by Overio ("we", "us", or "our"). Please read these Terms of Use (the "Terms") carefully before installing, accessing, or using the App. By using Stikoo, you acknowledge that you have read, understood, and agree to these Terms.

1. Scope

  • These Terms apply to the Stikoo iOS and Android Apps, their local sticker-journal features, on-device recognition, Enhanced Recognition, anonymous usage quotas, and related services.
  • TestFlight, Android beta distribution channels, preview, and other pre-release versions are also covered unless separate terms are provided.
  • The Privacy Policy forms part of the rules governing your use of Stikoo. For privacy matters, the Privacy Policy controls if there is a conflict.

2. Eligibility

  • You must have the legal capacity required by the laws applicable to you. Minors may use the App only with the involvement and consent of a parent or legal guardian where required.
  • If you use the App on behalf of another person or organization, you represent that you are authorized to accept these Terms on their behalf.

3. The Service

Stikoo allows you to:

  • take a photo or select one from your photo library;
  • separate the main subject and render it as a sticker on your device;
  • receive suggested titles, categories, tags, descriptions, and journal notes;
  • edit and save sticker images and related journal information locally;
  • browse and manage saved stickers by day and calendar date;
  • choose Quick Recognition for on-device use or Enhanced Recognition for cloud-assisted suggestions.

No account, subscription, or in-App purchase is required in the current version. Features, availability, usage limits, and supported platforms may change over time.

4. Recognition Modes and AI Features

4.1 Quick Recognition

Quick Recognition uses supported Apple on-device technologies and can operate without sending the selected image to Stikoo's recognition server. Results may be less detailed or differ from Enhanced Recognition.

4.2 Enhanced Recognition

  • Enhanced Recognition requires an internet connection and sends a processed image of the separated subject to the Stikoo recognition service and an AI service provider.
  • The current service may allow up to 30 successful Enhanced Recognition requests per anonymous App installation per day, resetting at 00:00 in the Asia/Shanghai time zone. We may adjust quotas, reset times, eligibility, or abuse controls when reasonably necessary to operate and protect the service.
  • Anonymous device-integrity verification (App Attest on iOS; Google Play Integrity or Android Keystore key attestation on Android), request signing, rate limiting, and other security checks may be required. Enhanced Recognition may be unavailable on unsupported, modified, compromised, or unverifiable devices.
  • If Enhanced Recognition is unavailable or the quota is exhausted, you may switch to Quick Recognition where supported.

5. AI Output and Your Review

  • Recognition suggestions are generated automatically and may be inaccurate, incomplete, inappropriate, outdated, or inconsistent.
  • Titles, categories, tags, descriptions, notes, confidence values, and other suggestions are provided for convenience only. You are responsible for reviewing and editing them before saving, sharing, publishing, or relying on them.
  • Stikoo does not provide medical, legal, financial, safety, authentication, valuation, or other professional advice. Do not rely on recognition results for high-stakes decisions.
  • AI services may produce similar or identical suggestions for different users, and we do not guarantee that suggestions are unique or free from third-party claims.

6. Your Content and Permissions

  • You retain any rights you lawfully hold in photos, sticker images, titles, notes, tags, and other content you provide or create through the App.
  • You grant us and our service providers a limited, non-exclusive, worldwide, royalty-free license to host, transmit, reproduce, and process content submitted to Enhanced Recognition solely as needed to provide, secure, troubleshoot, and maintain that feature, subject to the Privacy Policy.
  • You represent that you have all rights, permissions, and lawful bases needed to capture, upload, process, store, and use your content, including images of other people, private property, copyrighted works, confidential material, and personal information.
  • You are responsible for any content you save, use, export, publish, or share and for complying with applicable laws and third-party rights.

7. Acceptable Use

You must not:

  • use Stikoo for unlawful, fraudulent, abusive, harassing, deceptive, dangerous, or rights-infringing purposes;
  • submit content that you are not authorized to process, or use the App to violate privacy, portrait, publicity, intellectual-property, confidentiality, or other rights;
  • upload malware, malicious payloads, or content intended to exploit, disrupt, overload, probe, or damage the App or service;
  • automate requests, create artificial installations, manipulate quotas, replay assertions, bypass App Attest, evade rate limits, or otherwise abuse Enhanced Recognition;
  • reverse engineer, decompile, modify, tamper with, or circumvent security or usage controls, except to the extent such restriction is prohibited by applicable law;
  • misrepresent AI-generated suggestions as verified facts or use them in a way that creates a foreseeable risk of harm.

8. Local Storage, Deletion, and Backups

  • Saved journal entries are stored locally on your device in the current version and are not synced to a Stikoo account.
  • You are responsible for maintaining device backups if you want to preserve local data. App deletion, device loss, operating-system behavior, storage failure, or backup and restore actions may cause data loss.
  • Deleting a sticker removes it from the App's local database, subject to system backups and normal storage behavior. Uninstalling the App generally removes its local App container, but some key/credential storage, backup, or system-security data may be retained by iOS or Android platform mechanisms.

9. Third-Party and Platform Services

  • Stikoo may rely on Apple or Google platform services, Firebase Analytics, the GLM API provided by Beijing Zhipu Huazhang Technology Co., Ltd., and hosting or network providers.
  • Third-party services are governed by their own terms, privacy policies, availability, technical limits, and service decisions. We do not control and are not responsible for third-party services.
  • Your use of Apple devices, iOS, the App Store, backups, camera and photo interfaces, and App Attest is also subject to Apple's applicable terms; your use of Android devices, Google Play (where applicable), system backup, camera and photo-picker interfaces, and Google Play Integrity is also subject to Google's applicable terms.

10. Fees

  • The current version is provided without subscriptions or in-App purchases unless the App or App Store listing states otherwise.
  • We may introduce paid features or change the service model in the future. Any price, subscription term, renewal rule, cancellation method, and refund information will be disclosed through the applicable App Store or in-App purchase flow before you are charged.
  • Your mobile carrier, internet provider, or other third party may charge data or connectivity fees, which are your responsibility.

11. Intellectual Property

  • The App, including its software, interfaces, artwork, icons, animations, designs, documentation, algorithms, and branding, is owned by Overio or its licensors and is protected by applicable intellectual-property laws.
  • Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the App for its intended purpose.
  • You may not copy, distribute, sell, sublicense, publicly display, or create derivative works from the App or its proprietary materials except with permission or as allowed by law.

12. Updates, Availability, and Termination

  • We may update, change, suspend, restrict, or discontinue any part of Stikoo to improve the product, address security or legal issues, manage costs, prevent abuse, or respond to third-party service changes.
  • We do not guarantee that any feature, model, quota, category, output format, language, or service endpoint will remain available.
  • You may stop using Stikoo at any time by deleting the App.
  • We may restrict or terminate access to Enhanced Recognition if we reasonably believe you have violated these Terms, created security or legal risk, or abused the service.

13. Disclaimers

  • Stikoo is provided on an "as is" and "as available" basis to the maximum extent permitted by law.
  • We do not warrant that the App will be uninterrupted, error-free, secure, compatible with every device, or that recognition results will be accurate or suitable for your purposes.
  • You are responsible for protecting your device, reviewing saved content, maintaining backups, and deciding whether the App and its outputs are appropriate for your use.

14. Limitation of Liability

To the maximum extent permitted by applicable law, Overio and its licensors and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of data, profits, goodwill, business, or opportunities arising from or related to Stikoo. Where liability cannot be excluded, our aggregate liability will not exceed the amount you paid to use Stikoo during the twelve months before the event giving rise to the claim, or the minimum amount required by applicable law if the App was free.

Nothing in these Terms excludes rights or liabilities that cannot lawfully be excluded or limited.

15. Indemnity

To the extent permitted by law, you agree to be responsible for claims, losses, and reasonable costs arising from your unlawful content, your violation of third-party rights, your misuse of the App, or your material breach of these Terms.

16. Changes to These Terms

We may update these Terms when the App, service, law, or business model changes. Material changes will be communicated through the App or our official website where reasonably practicable. Continued use after the effective date of updated Terms constitutes acceptance to the extent permitted by law; if you do not agree, stop using and delete the App.

17. Governing Law and Disputes

These Terms are governed by the laws of the People's Republic of China, without regard to conflict-of-law rules, unless mandatory law in your jurisdiction requires otherwise. The parties should first attempt to resolve disputes through good-faith negotiation. If a dispute cannot be resolved, it may be submitted to a court with jurisdiction where Overio is established, except where applicable law gives you another mandatory forum.
