The short version
Knowra is a curiosity feed. We need just enough data to make the feed feel personal and to keep the service running — nothing more. We don't sell your data, we don't share it with advertisers, and we don't track you across other apps.
What we collect
- An anonymous device ID. Generated on first launch and stored in your device's secure storage. We use it to remember which cards you've seen so we don't serve the same article twice.
- Swipe events. Impressions, saves, skips, opens. Used to tune what shows up in your For You tab. Stored alongside your anonymous device ID.
- Topic preferences. If you toggle topics on or off in Settings, that choice is sent with feed requests so the algorithm knows what to favor. Stored on-device and in our database.
- Saved articles & collections. Stored on your device. We don't sync them to our servers unless you sign in (sign-in is currently disabled in the public release).
- Push notification token (optional). Only if you explicitly opt in to notifications. Used to deliver the daily article ping; revoked the moment you turn notifications off.
What we don't collect
- No IDFA, IDFV, or advertising identifiers. Knowra does not show ads or share data with ad networks. You will never see an App Tracking Transparency prompt.
- No real identity. No name, no phone number, no email unless you choose to sign in (currently disabled).
- No location data. We don't request location permission and we don't infer location from your IP.
- No contacts, photos, or microphone access. We don't use them.
Third parties we share data with
We use a small set of vendors to run the service. Each receives only what they need to do their job.
- Anthropic — generates the short “hooks” displayed under article titles. We send the article title and description; we don't send your device ID or any user data.
- Wikimedia (Wikipedia) — the source of every article. Knowra fetches article metadata on your behalf. Your IP is not forwarded; requests come from our server.
- Cloudflare Images — stores and serves the article hero images. Standard CDN access logs apply.
- Neon (Postgres) — stores card metadata, your anonymous device ID, and your swipe events.
- Upstash (Redis) — caching and rate limiting.
- Apple Push Notification Service / Firebase Cloud Messaging — only if you've opted in to notifications.
Retention
Swipe events older than 90 days are deleted automatically. Saved articles live as long as you keep them. Your anonymous device ID is deleted when you uninstall the app or clear app data.
Children
Knowra is rated 13+. We don't knowingly collect data from anyone under 13. If you believe a child has used Knowra, email us and we'll remove the associated device ID and events on request.
Your rights
You can delete your local data at any time by uninstalling the app or clearing app data in your phone's settings. To request deletion of server-side data associated with your device, email jheremiah.dev@gmail.com with the word “delete” in the subject. Include your device ID (Settings → About in the app) so we can find your data. We'll confirm deletion within 30 days.
If you're in the EU, UK, or California, you have additional rights under GDPR / CCPA (access, rectification, portability, objection). Same email, same response time.
