Privacy policy
Last updated 11 November 2026
Wren collects as little as it can. There are no ads, no tracking and no analytics, and we never sell your data.
Wren is made by Siobhan, an independent developer in Canada ("we" in this policy). If you have any question about your data, email hello@wearwren.app.
You can use every part of Wren without signing in. Your colours, which items they belong to, your saved outfits, the outfits you mark as worn and your settings are stored only on your phone. We can't see them. Deleting the app deletes them.
Signing in keeps your wardrobe safe and lets you use it on another phone. When you sign in we store:
This is stored with Supabase, our database provider, and only you can read your own data from the app.
When you ask Wren why colours work together, or it writes a verdict on an outfit, it sends the colour names, which items they are and the colour rule to Anthropic, the company that makes the AI model, to write the text. Nothing that identifies you (no name, email or photo) is sent. Under its commercial terms, Anthropic doesn't use this to train its models.
If you use Send feedback, we receive your note, any screenshot you attach, the name you type (optional), which screen you were on, the app version, your phone model and system version, and whether you were signed in. We use this only to fix and improve Wren. If you'd like your feedback deleted, email us.
If you test Wren through Apple's TestFlight, Apple may also share crash reports and feedback with us under Apple's own privacy policy.
Some privacy laws, including in the UK and EU, ask us to say why we can use each kind of data:
These providers may store and process data in the United States and other countries. They only use it to provide their service to us.
We keep your account and wardrobe until you delete your account. Feedback is kept while it's useful for improving Wren, and deleted on request.
In the app, go to Settings → Account → Delete account. This permanently deletes your account and everything stored with it: your email address, wardrobe, saved outfits and worn history. Data on your phone is cleared too. You can also email us and we'll do it for you.
You can ask for a copy of your data, ask us to correct it, or ask us to delete it, by emailing hello@wearwren.app. We'll reply within 30 days. Depending on where you live, you may also have the right to complain to your data protection authority.
Wren isn't designed for children under 13, and we don't knowingly collect data from them. If you think a child has created an account, email us and we'll delete it.
If we change this policy, we'll update the date at the top. If a change affects how we use your data, we'll tell you in the app first.
