Privacy Policy

1. Information we collect

ALYGN ("the Service") collects the following:

· Account: email address, nickname; and the email/name provided by Google or Kakao when using social login.

· Analysis history: symmetry score, asymmetry type/level, per-metric measurements, and analysis time.

· Browser storage (localStorage): language preference, login session, device analysis records, and activity and routine completion logs.

2. Face photos (important)

Photos you take or upload are analyzed only on your device (in the browser) and are never sent to or stored on our servers.

Guest analysis numbers (score, type, metrics) are stored in this browser. New analyses made while signed in are saved to the account and an account-specific device cache; the history page retries synchronization after connection failures. Guest records are not automatically uploaded to an account.

3. Purpose of use

· Account management (identification, login)

· Core features such as keeping analysis history and progress tracking

· Service improvement

4. Retention and deletion

Personal data is deleted without delay upon account deletion.

Both record deletion and account deletion are available directly on My Page.

The latest result photo is temporarily kept in this tab’s sessionStorage and is cleared when you choose to analyze again from the result or log out. Clear the browser’s site data to remove device records and caches. Deleting an account also clears its cache on this device; separate guest records remain.

5. Processors and third parties

We use the following processors to operate the Service:

· Supabase: authentication and data storage

· Vercel: web hosting

· Google, Kakao: social login

· Google Analytics: visit statistics (page views, traffic sources — non-identifying aggregates)

We do not share personal data with third parties except as required by law.

6. Cookies and advertising

Browser storage is used to keep you logged in and remember settings.

We use Google Analytics to collect visit statistics (page views, traffic sources, device type) for service improvement. These statistics do not identify individuals.

If ads (Google AdSense) are shown, Google and its partners may use cookies to serve personalized ads based on your visits. You can opt out at Google Ads Settings (https://adssettings.google.com).

7. Your rights

You may request access, correction, or deletion of your personal data at any time.

Analysis records and your account can both be deleted directly on My Page.

8. Changes

Any changes to this policy will be posted on this page with the effective date.
