SubSentry

For iPhone · Coming soon

Know what renews before it does.

SubSentry reads your billing emails, not your inbox. It finds the subscriptions you’re paying for, shows what they cost each month, and reminds you before the next charge.

What it does

Stop paying for things you forgot about.

Connect Gmail once, check what we found, and SubSentry keeps watch from there.

Point at today. The steps are the days you have left.

  1. Finds your subscriptions

    If you choose to connect Gmail, SubSentry searches it for billing emails such as receipts, renewals, free trials, price changes and cancellations, and suggests the subscriptions it finds.

  2. Nothing counts until you say so

    Every suggestion waits for you to confirm it. Edit or add subscriptions by hand, and later scans never overwrite your changes.

  3. A nudge before you pay

    Get reminded before a renewal, or before a free trial turns into a charge, while there’s still time to cancel.

  4. Totals you can trust

    Monthly and yearly spending, per currency. Different currencies are never added together.

  5. Estimates are labelled as estimates

    When an email doesn’t give an exact date or amount, SubSentry works it out from the billing cycle and tells you it did.

Getting started

Set up in about a minute.

Your Gmail

We read receipts, not your inbox. And we keep the details, never the emails.

fig. 3 · receipts only rest
Receipts give up their details. Other mail stays sealed.
What we read
Only messages that match billing searches: receipts, invoices, renewals, trials, price changes and cancellations. Other email isn’t opened. Access is read-only.
What we keep
The service name, plan, price, billing dates and sender’s domain, plus a reference to the email they came from. We don’t store full emails.
What we never do
Sell your email data, use it for advertising, or use it to train AI models. Gmail access happens on our servers, never on your phone.
What you control
Disconnect Gmail in Settings any time and we revoke access immediately. Export your data, or delete your account and everything we stored.

SubSentry’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Full details are in our Privacy Policy.
