SubSentry — Subscription Sentinel
A sentinel at the gate of your wallet: see every renewal coming before it charges you.
What it does
- The sentinel's watch. Escalating reminders before each renewal — including a Live Activity countdown on your Lock Screen, so a charge never ambushes you again.
- Magic import. Point it at a subscription screenshot or receipt: on-device OCR and Apple's on-device language model turn it into a tracked subscription. Nothing leaves your iPhone.
- Honest math. Monthly and yearly totals, per-service cost, and what canceling would save you.
- Yours forever. Free for up to 5 subscriptions. One purchase of $4.99 unlocks unlimited — no subscription to manage your subscriptions. That would be ironic.
- Private by architecture. No account, no server, no analytics. Your data lives on your device and syncs through your own iCloud.
- Bilingual. English and 中文, written by hand, not machine-translated.

Privacy Policy
Last updated: July 2026
SubSentry is built so that I cannot see your data, even if I wanted to:
What we collect
Nothing. SubSentry has no account system, no analytics SDK, no tracking, and no server operated by the developer. The app never transmits your data to us or to any third party.
Where your data lives
Everything you enter or import stays in the app's local database on your device. If you enable iCloud sync, your data is stored in your personal iCloud container, encrypted and managed by Apple, accessible only to your Apple Account. The developer has no access to it.
On-device intelligence
Screenshot and receipt import runs entirely on your device, using Apple's Vision framework and on-device Foundation Models. Images and text are never uploaded anywhere.
