1. What Sol is

Sol is a daily theme app. Each day has one prompt. You may post a photo and a short caption to today. At midnight that day closes.

2. Information we collect

We do not require precise location, contacts, or health data. This version does not sell coins or process payments.

3. How we use it

We do not sell your personal information. We do not use your data to track you across other companies’ apps or websites for advertising.

4. Who can see your posts

Posts and comments are visible to other Sol users. Do not post information you want to keep fully private.

5. Sharing

We use infrastructure providers (for example, cloud hosting, email delivery, and NetEase Yunxin for push delivery) only to run Sol. We may disclose information if required by law.

6. Retention

We keep account and post data until you delete your account, or until we remove it for policy or legal reasons. Closed days remain in Archive unless the post or account is deleted.

7. Your choices

You may edit your profile in Settings, turn Daily prompt and Comments notifications off, block other users, and delete your account in Settings → Delete account. That removes your profile, answers, and comments. You may also email wyl2023666@gmail.com.

8. Children

Sol is not directed at children under 13. We do not knowingly collect personal information from children under 13. See our Child Safety page.
