Privacy Policy
Sewzy · Last updated 22 September 2026
Sewzy ("the app") is a sewing-pattern and learning app for iPhone. This policy explains what the app does and doesn't collect.
What we collect
- Nothing tied to your identity. The app has no accounts and does not ask for your name, email or address.
- Purchases are handled by Apple and our subscription provider RevenueCat, which receives an anonymous app-generated user ID and your purchase status so your subscription works and can be restored. See RevenueCat's privacy policy.
- Sewing coach. When you ask the coach a question, the text (and a photo, if you attach one) is sent to our server and forwarded to Google's Gemini API to generate the answer. The same applies to the photo search (Find a pattern from a photo): the photo you pick is sent the same way only to suggest the closest patterns, and it is not stored. Messages are not stored beyond what is needed to answer and to enforce daily limits (a count per anonymous ID). Do not include personal information in your questions.
- Content downloads. Pattern PDFs and images are downloaded from our content server; standard server logs (IP address, time, file) may be kept briefly for reliability.
What stays on your device
Your measurements, fabric stash, project progress, lessons completed, badges, photos you add and settings are stored only on your device (and in your iCloud backup if enabled). We cannot see them.
Tracking & advertising
Sewzy contains no ads and no third-party tracking or analytics SDKs. We do not sell or share data.
Children
Sewzy is not directed at children under 13 and we do not knowingly collect data from them.
Your choices
Delete the app to remove all on-device data. Manage or cancel subscriptions in iOS Settings → Apple ID → Subscriptions. To ask us to delete server-side coach usage records for your anonymous ID, email us.
Changes
We'll update this page when the policy changes; the date above tells you when.
