Summer93

Privacy Policy

Last updated: 25 May 2026 · Version 1.1.0

Short version

Summer93 is a baseball almanac. It does not require an account, does not ask for personal information, and does not sell or share any data with advertisers. The only data it collects is the minimum needed to deliver push notifications when the Toronto Blue Jays score and to diagnose crashes.

What we collect

Three categories of data, all anonymous:

• An anonymous device identifier (a UUID generated on first launch, stored in the iOS Keychain on your device). It is how the server knows where to send push notifications. It is not tied to your name, email, Apple ID, or any other personal information, and does not sync to iCloud.
• An Apple Push Notification service (APNs) token, issued by Apple on each install, used to route a notification to your device. We forward push payloads to Apple; Apple delivers them.
• Crash and error diagnostics via Sentry — a stack trace, the route that errored, the build and iOS version, and the failure tag. No personally identifying information is included.

What we do not collect

• Your name, email, or Apple ID.
• Your location, contacts, photos, calendar, health, or financial data.
• Browsing history — the News tab opens articles in Safari’s own isolated view.
• Advertising identifiers (the IDFA). Summer93 has no ads.

How push notifications work

You opt in once on the Schedule tab. The app registers your APNs token with our backend over HTTPS, authenticated with a per-install HMAC signature. When the Jays score during a live game, our backend checks the MLB Stats API, diffs the score, and asks Apple to deliver a notification to every opted-in device. We only ever see your anonymous UUID. Turn notifications off any time in iOS Settings → Notifications → Summer93.

Where the data lives

• Device identifier and APNs token: Upstash (managed Redis), United States.
• Crash diagnostics: Sentry (US region), 90-day default retention.
• The backend itself: Vercel, United States.

Data retention and deletion

To have your anonymous device identifier and APNs token removed now, email the address below with your device’s UUID (find it in Summer93 → Settings → About → Device ID). We remove it within 7 days. Data also auto-deletes when you uninstall — Apple tells our backend the token is dead and we drop the record, typically within 24 hours.

Children

Summer93 is rated 4+ and does not knowingly collect data about anyone, including children under 13. Contact us to have a device’s anonymous identifiers removed.
