Do you need to connect your bank to track subscriptions?

No. A bank connection is one way to find subscriptions, not a requirement for tracking them, and it’s worth understanding the trade before you hand any app your transaction history.

What a bank-linked tracker actually does

Apps that ask you to “connect your bank” use an open-banking provider to read your transaction history, then guess which recurring charges are subscriptions. That buys you automatic discovery: charges appear without you typing anything.

What you trade for it:

• Your full transaction history is shared, not just subscriptions. The connection reads your spending, and the app’s privacy policy, not your bank’s, governs what happens to it. Business models built on “free” finance apps often involve monetising exactly this data in aggregated form.
• Detection is a guess. Irregular billing dates, annual charges, family members’ payments and one-off purchases from the same merchant all confuse it. You end up correcting the list by hand anyway.
• It only sees one account. Subscriptions paid from another card, a partner’s account, PayPal or an app store bundle are invisible to it.

Some services in this market also charge a subscription of their own to watch your subscriptions, which has a certain irony to it.

What tracking actually requires

A subscription is a name, a price, a billing cycle and a renewal date. Four fields. Capturing them doesn’t need your bank credentials; it needs a decent way to enter and remember them:

• A catalogue for the common cases: pick Netflix, confirm the price, done in seconds.
• Manual entry for the rest, including the obscure annual ones no detector finds.
• A receipt scan for the paper trail: point the camera, let the phone read the details.

Once the list exists, the useful work is the same either way: one honest monthly and yearly total, and a reminder before each charge so nothing renews silently.

The private version of this

SubHelm is built on the second model, all the way down. You add subscriptions from a 200+ service catalogue, by hand, or by scanning a receipt, and the receipt is read on your device, never uploaded. There’s no account, because there’s no server to send your data to; the list lives on your iPhone and syncs through your own iCloud. Nobody, including us, can see what you subscribe to.

The one-time setup cost is real: entering your subscriptions takes a few minutes rather than zero. In exchange, nothing about your finances leaves your phone, and the list includes everything you pay for, not just what one bank account happens to show.

Choosing between the two

Connect a bank if automatic discovery matters more to you than where your transaction history goes, and you’re comfortable with the provider’s policy. Track manually if the idea of a subscription app reading your bank account is exactly the kind of thing you’re trying to have less of. Either way, the yearly total is the number to look at, and the reminder before the charge is the feature that actually saves money.
