Terms of Use

1. Acceptance

PicSeek (the “App”) is developed and provided by Charonyu (App Store seller name: Cheng Yu Chiang, Taiwan). By downloading or using the App you agree to these terms and to the Privacy Policy. These terms supplement Apple’s standard Licensed Application End User License Agreement; where they conflict, and to the extent the law allows, Apple’s agreement prevails. If you do not agree, please do not use the App.

2. The service

The App lets you search your iPhone photo library in natural language, in Chinese or English, by date, place, what is in the picture and any text in it. Indexing and search run on your device. We may add, change or remove features. Results come from automatic recognition and may be incomplete or imprecise; they are for finding photos only.

3. Accounts

The App needs no account. The search index is stored only on your device and is not synced to other devices.

4. Free tier and paid plans

• The free tier can index up to 1,000 photos.
• Personal, Plus and Max are auto-renewing yearly subscriptions that raise the indexing limit to 20,000, 50,000 and 100,000 photos (in Taiwan NT$399, NT$699 and NT$999 per year; other regions as shown in the App Store).
• You are charged through your Apple Account when you confirm the purchase. Unless auto-renew is turned off at least 24 hours before the end of the current period, the subscription renews automatically on the same plan, and the renewal is charged within 24 hours before the period ends.
• You can manage or cancel at any time in Settings > Apple Account > Subscriptions on your device; cancelling takes effect at the end of the current billing period.
• Payment, refunds and transactions are handled by Apple; request refunds through Apple’s refund policy and process. If Apple refunds or revokes a purchase, the paid limit is turned off and free features are unaffected.
• With the same Apple Account you can use “Restore purchases” on the purchase screen.
• After a subscription expires, is cancelled or is not renewed, the index you built stays on your device and what you can search returns to your current plan’s limit (1,000 photos on the free tier); resubscribing restores it without re-analyzing existing photos.

5. Your content

The photos in your library belong to you. Use the App only on photos you have the right to process, and respect other people’s privacy and rights.

6. Open-source components

The App includes Google’s SigLIP 2 image-understanding model under the Apache License 2.0; we converted it to Core ML and compressed its weights so it runs on iPhone. The full license and a statement of changes are in the App under Settings → Open-source licenses; the original model is at huggingface.co/google/siglip2-base-patch16-256.

7. Prohibited conduct

You agree not to reverse engineer, decompile or disassemble the App (except where the law expressly allows), use it for unlawful purposes, try to bypass the purchase mechanism, or redistribute or resell the App.

8. Disclaimer

The App is provided “as is”. To the extent the law allows, we do not warrant that it is free of errors or interruptions, or that every photo will be correctly recognized or found.

9. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special or consequential damages arising from using or being unable to use the App. Liability that cannot be excluded or limited by law is not affected by this section.

10. Changes

We may update these terms; for material changes we will update the date on this page and give reasonable notice. Continuing to use the App after a change means you accept the new terms.
