Subgrove's answer

Subgrove started with a question I couldn't get a good answer to: why does an app need my bank login to show me a list I could write on an index card? The tracker I wanted didn't exist, so I built it. No bank connection, no data to sell, no app store — it installs from the browser and works on whatever phone you happen to own. And a one-time price, because I wasn't going to ship a subscription that tracks your subscriptions.

Subgrove's answer

Subgrove never asks for your bank. Almost every subscription tracker opens by connecting your account through an aggregator like Plaid, which reads your entire transaction feed to find a dozen recurring charges. Subgrove skips that: you enter subscriptions yourself. There's no bank credential to leak, no transaction history to monetise, and no geographic lock-out — bank-linked apps only work where their banking rails reach (Rocket Money, for instance, is US-only by its own documentation). It's also a PWA, so a single install works on iPhone, Android and desktop, and it works offline.

Subgrove's answer

Three reasons. Privacy by architecture — there's no bank connection to trust, because there isn't one. It works everywhere — no country restriction and multi-currency support, so USD and GBP subscriptions don't quietly misreport your total. It's genuinely cross-platform — most polished trackers are one platform only (Bobby is iOS-only, Subby is Android-only), which makes them useless for a mixed-device household; Subgrove is the same app on both. Pricing is $1.99/month, $10/year, or $15 once for lifetime — not another subscription to track your subscriptions.

Subgrove's answer

People who want to track subscriptions without handing a fintech app live access to their bank account. In practice that's four overlapping groups: privacy-conscious users who refuse Plaid; people outside the US locked out of Rocket Money and similar apps; mixed-device households and couples where one person has an iPhone and the other Android; and people with subscriptions in multiple currencies — expats, freelancers with foreign clients — whose real monthly total drifts with the exchange rate.
