개인정보 처리방침

HairDiary ("we", "our", or "us") is committed to protecting your privacy. This policy explains what data is collected, how it is used, and your rights.

1. Data We Collect

HairDiary stores all data you enter — including hair care logs, daily check-ins, product entries, photos, and notes — locally on your device and, if you enable iCloud, in your personal iCloud account.

We do not collect or store any personal data on our own servers. We have no access to your diary entries, photos, or personal information.

From version 2.2 you can scan a product's barcode when you add it. Only the barcode number is then sent to Open Beauty Facts, an open database of cosmetics, to look up the product's name, brand and photo. Nothing else is sent, and scanning is optional.

2. iCloud Sync

If you use iCloud sync (available with HairDiary Pro), your data is synced via Apple's iCloud service. This data is stored in your personal iCloud account and governed by Apple's Privacy Policy. We cannot access your iCloud data.

3. Analytics

From version 2.1 the HairDiary app sends anonymous usage statistics through TelemetryDeck, a privacy-first analytics service based in the EU. It tells us things like whether onboarding was finished, how many logs have been saved and from where (the app, the widget, Siri or a notification), and whether Insights or the subscription screen was opened. It never includes anything you log: no notes, photos, products, ratings or how your hair feels.

The statistics are not linked to you or your Apple ID and are not used for advertising or tracking. TelemetryDeck only receives a one-way hashed, random identifier, so we cannot tell who a user is. You can turn the statistics off at any time in the app under Settings → Privacy → Share anonymous usage statistics.

Apple may also provide us with aggregate App Analytics (such as crash reports) if you have chosen to share them with app developers. This website does not use analytics.

4. In-App Purchases

Purchases (HairDiary Pro subscriptions) are processed entirely by Apple via the App Store. We do not receive or store your payment information. Subscription status is managed with RevenueCat, which receives an anonymous app user ID and your purchase history, and, if you came from an Apple Search Ads ad, which ad campaign that was. See Apple's Privacy Policy for details.

5. Children

HairDiary is not directed at children under the age of 13. We do not knowingly collect information from children.

6. Contact

7. Changes

We may update this policy from time to time. The date at the top of this page reflects the latest revision. Continued use of the app after changes constitutes acceptance of the updated policy.
