Privacy Policy

This Privacy Policy describes how DailyMath ("we", "our", or "us") collects, uses, and shares information when you use dailymath.co and the related app at app.dailymath.co (together, the "Service").

1. Information we collect

Account information. When you sign in with Google or Apple, we receive your name and email address from the identity provider (and a profile image, in the case of Google). If you choose Apple's "Hide My Email" option, we only receive a private relay address — we never see your real email.

Activity data. When you solve problems, we record the problems attempted, answers submitted, time spent, hints used, and whether the answer was correct. This is necessary to compute streaks, ratings, and personalized recommendations.

Optional profile data. If you choose to share your country, grade level, school, or city, we store these to localize leaderboards and recommend appropriate problems.

Analytics. We use Visitors.now to collect aggregate page-view and interaction data on the marketing site (dailymath.co). We do NOT load tracking on the app surface (app.dailymath.co). With your consent, we set a persistent cookie so we can recognize repeat visitors across sessions; without consent, we use the script in anonymous mode only. See our Cookie Policy for details.

2. How we use information

• To operate the Service, including authenticating you and saving progress.
• To compute and display streaks, ratings, and personalized problem recommendations.
• To improve the Service — measuring which problems work well, fixing bugs, prioritizing features.
• To communicate with you when you've explicitly opted in (e.g., daily email).
• To detect abuse and prevent fraudulent or unauthorized activity.

3. Sharing

We do not sell your personal data. We share information only with:

• Service providers we use to run the Service: Convex (database + auth), Vercel (hosting), Visitors.now (analytics on the marketing site only). Each processes data only as needed.
• Legal authorities when required by law or to protect our or others' rights, property, or safety.

4. Your rights

Under GDPR and similar laws you have the right to access, correct, delete, or export your personal data. To exercise any of these rights, email hi@dailymath.co. We respond within 30 days.

You can withdraw analytics consent at any time using the "Cookie preferences" button in our footer, which clears the persistent analytics cookie.

5. Data retention

We retain account data and activity data for as long as your account exists. If you delete your account, we delete the associated data within 30 days, except where we are legally required to keep it longer.

6. Children

DailyMath is intended for users aged 13 and over. If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us and we will delete it.

7. Changes

We may update this policy. The "Last updated" date at the top reflects the most recent change. Material changes will be announced on the home page or by email.
