Your data, your control

Privacy Policy

Radia is built privacy first. Your photos and skin profile are used to power your analysis and routine, nothing else. We do not sell your data and we do not use it for advertising.

Last updated: 8 August 2026

1. Overview

Radia ("Radia", "we", "us") helps you read your skin and build a cosmetic skincare routine. This policy explains what we collect, what we do with it, and what we never do. Plain language, because that is the whole point of the app.

2. The short version

  • Your selfie is analyzed, never stored, and never used to train any model. It is sent to our analysis service, read once, and discarded. We do not keep the image, on our servers or on your device.
  • Your skin scores and routine live on your device.
  • Your photo journal stays only on your device. Journal photos are never uploaded to our servers, and you can delete all of them at any time.
  • We do not sell your data, show ads, or track you across other apps.

3. What we collect

Your selfie (biometric data). A photo of your face is biometric information, and we treat it that way. You consent before any capture. The photo is sent over an encrypted connection to our backend, which passes it to an AI vision service (Anthropic) that returns cosmetic appearance scores. The image is processed in memory and is not persisted on our servers or theirs, and Anthropic does not train on API traffic. Only the resulting numbers come back to your device.

Your skin data. Scores, your routine, and your streaks are stored on your device.

Your photo journal (on-device only). The photo journal is a daily-photo habit feature, and it is separate from the scan. When you save a journal photo, it is written only to your own device, inside the app's protected storage. Journal photos are never uploaded to our servers or to any third party. You can delete any photo, or delete all of them at once, from the delete-all control in Profile. Deleting the app also removes them. Because these photos never leave your device, they are not "collected" under Apple's App Privacy definitions.

Account information. If you create an account, our authentication provider (Clerk) stores your email and, if you use Sign in with Apple or Google, the identifier those services return. We use this only to sign you in and to sync your subscription.

Subscription status. Purchases are handled by Apple. Apple tells us only whether your subscription is active. We never see your card or payment details.

Product analytics (optional). If analytics is enabled, we record anonymous usage events about app flow, for example that a scan happened or which screen you reached, to improve the app. These events never include your selfie, your score, or any biometric data.

We do not require your real name, phone number, or precise location to use Radia.

4. What we never do

  • Store or keep your selfie.
  • Use your images to train models.
  • Sell or rent your personal data.
  • Show third-party ads, or track you across other apps or websites.
  • Diagnose disease. Radia is a cosmetic appearance tool, not medical advice.

5. Who processes your data

  • Convex — our backend. Routes the scan request; does not store the image.
  • Anthropic — the AI vision analysis. Processes the image, does not retain it or train on it.
  • Clerk — sign-in (email, Apple and Google identifiers).
  • Apple — subscription payments.

6. Your choices and rights

  • Delete your data. You can delete your account and your on-device data from within the app, in Profile settings, including a delete-all control for your on-device photo journal. Deleting the app also removes on-device data.
  • Access. Because your skin data lives on your device, you already hold it.
  • Depending on where you live, for example the EU and EEA under GDPR, or California under CCPA and CPRA, you may have rights to access, correct, or delete personal data, and to object to processing. Email us and we will honour applicable requests.

7. Retention and deletion

Your selfie is not retained at all: it exists only for the moments it takes to analyze it. Your skin scores, routine and journal photos remain on your device until you delete them or remove the app. Account information held by our sign-in provider is deleted when you delete your account.

8. Security

Images are sent over encrypted connections and processed in memory. On-device data, including journal photos, sits inside the app's protected storage container. No system is perfect, so if you believe your account has been compromised, contact us and we will act.

9. Children

Radia is not directed to children under 13, or the minimum age in your region if it is higher, and we do not knowingly collect their data. The app asks for your age at sign-up and does not permit use under 13.

10. Cosmetic guidance, not medical advice

Important: Radia provides cosmetic skincare guidance only. It is not a medical device, it does not diagnose, treat, or prevent any medical condition, and it is not a substitute for professional medical advice. If you have a skin concern that may be a medical issue, please consult a qualified healthcare professional.

11. Changes

If we change this policy we will update the date above and, for material changes, notify you in the app.
