Barnacle
Last updated: 25 August 2026
Plain answers to the things people actually ask about subscription trackers, including the ones where the honest answer is no.
Yes. Barnacle is one. You enter subscriptions by hand rather than having them detected, which is the trade that removes the need for a bank connection. Typing a name fills in the usual price from a catalogue of 243 services, so it takes a few seconds per subscription.
Barnacle costs $5.99 once. There is no renewal and the price does not rise later. It is free to download and the free version tracks five subscriptions, which is enough to decide whether it earns a place on your phone.
Because detecting subscriptions automatically requires reading your transactions, and banks do not offer a way to share only the subscription ones. Granting read access to a tracker usually means granting an aggregator in the middle continuing access to your full transaction history, not a one-time look at the subscriptions in it.
Not really, and Barnacle does not claim to. It records that you cancelled something and links to the provider's own cancellation page. Services that offer to cancel on your behalf are generally sending messages as you, which requires far more access than tracking does.
Yes. There is no server to reach, so everything except the App Store billing check works with no connection at all. Your subscriptions live in a database on the device and are never uploaded.
You export an encrypted file and import it on the new phone. Because there is no server there is no sync and no cloud backup, which is a real cost of the design rather than an oversight.
No. There is no analytics package and no crash reporting installed, so there is nothing to opt out of. A static scan fails the build if any first-party file even names a network primitive, and the test suite runs with those functions replaced by traps that throw.
No. It is iOS only, and needs iOS 16.4 or later. There is no Android version and no date for one.
