1. Introduction
Welcome to Crystal Keeper: Stone Journal (“Crystal Keeper” or the “App”), a mobile application developed and operated by Sean, an independent developer (“Developer,” “we,” “us,” or “our”). These Terms are a legal agreement between you and the Developer governing your use of the App and related services.
By downloading, installing, accessing, or using the App, you agree to these Terms and our Privacy Policy. AI-generated identification suggestions may be inaccurate, incomplete, or unreliable and must not be relied upon for commercial, financial, scientific, safety-related, or other consequential decisions.
2. Eligibility
The App is not directed to children. You must be at least 16 years old, or the higher minimum age of digital consent in your country, to use it.
3. License
Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the App on a device you own or control for personal, non-commercial use.
4. AI Identification & Third-Party Processing
When you submit a photo for identification, it is transmitted through our proxy server and processed by third-party AI services, currently Alibaba Cloud Model Studio / Bailian, including Tongyi Qianwen models, and potentially other providers in the future.
- Submitted images are processed to generate identification suggestions.
- Provider processing is governed by its own terms and privacy practices.
- Automated results may be inaccurate or misleading.
- Do not submit images containing people, faces, documents, location-revealing details, or sensitive information.
5. Your Content
You retain ownership of the photos, text, and information you create. You grant us and service providers a limited license to host, transmit, and process that content only as needed to operate the App.
You are responsible for your content and must have the necessary rights to submit it.
6. Local Storage
Your collection is stored locally on your device. We do not currently maintain user accounts or a central collection database.
If you delete the App, lose your device, or experience device failure, locally stored data may be lost. You are responsible for backing up your device.
7. Acceptable Use
- Do not use the App unlawfully or submit illegal, infringing, obscene, or privacy-violating content.
- Do not reverse engineer or attempt to derive source code except where law permits.
- Do not disrupt, overload, automate access to, or bypass security and usage limits.
- Do not resell, sublicense, or commercially exploit the App or its results.
8. Intellectual Property
The App’s design, interface, code, graphics, and related materials—excluding your content and third-party materials—belong to the Developer and are protected by intellectual-property laws.
9. Third-Party Services
The App relies on services including AI providers and Apple’s App Store. Their own terms and privacy policies govern your use of those services.
10. Subscriptions, Purchases & AI Limits
Crystal Keeper may offer monthly or annual auto-renewing Pro subscriptions. Apple processes payments, renewals, cancellations, refunds, and Restore Purchases. Pro access normally ends when Apple reports that an entitlement has expired, been refunded, or revoked.
Current Pro benefits include unlimited locally stored entries, Pro sharing templates, and up to 100 successful AI identifications weekly. Free users may store up to 10 entries and receive up to 15 successful AI identifications weekly. Allowances reset Monday at 00:00 UTC; failed identification requests do not consume them. Security, anti-abuse, capacity, and cost controls may also temporarily restrict availability.
11. Disclaimers; No Warranties
To the fullest extent permitted by law, the App is provided “as is” and “as available,” without warranties. We do not warrant uninterrupted, secure, error-free service or accurate identification results.
12. Limitation of Liability
To the fullest extent permitted by law, the Developer is not liable for indirect, incidental, special, consequential, or exemplary damages or loss of data, profits, or goodwill. Aggregate liability will not exceed the greater of what you paid in the prior twelve months or USD $50, except where law does not permit this limit.
13. Indemnification
To the extent permitted by law, you agree to hold the Developer harmless from claims, damages, liabilities, and reasonable expenses arising from your use, content, or violation of these Terms or third-party rights.
14. Termination
You may stop using the App at any time. We may suspend or terminate access if you violate these Terms or if the App is discontinued. Provisions that should survive termination will remain effective.
15. Governing Law & Disputes
These Terms are governed by the laws of the People’s Republic of China. Disputes will be resolved in competent courts in Shanghai, China, unless mandatory consumer laws in your residence require otherwise.
16. Apple App Store Terms
These Terms are between you and the Developer, not Apple. Apple is not responsible for the App, content, maintenance, support, or most related claims. Apple and its subsidiaries are third-party beneficiaries and may enforce these Terms.
17. Changes to These Terms
We may update these Terms. Material changes will be reflected in the “Last updated” date and made available in the App. Continued use after changes take effect constitutes acceptance.
