Stash is a cash-stuffing budgeting app. You type your money in yourself — Stash never links to your bank. This page mirrors exactly what the app does with your data.
You type everything in yourself. Stash never connects to your bank and never pulls from your accounts.
On your device, plus one copy on our server (Supabase) so the app can sync and a new phone can restore it. By default that copy belongs to an anonymous account only your device can access. Sign in with Apple to tie it to you; either way, only your account can read it, and it is never shared with anyone else.
Stash has no analytics SDKs, no ad networks, and no data brokers. We can’t see your spending and wouldn’t want to.
We receive only what Apple shares — at most your email, used as your account label. Hide My Email works fine.
Subscriptions (Stash Pro) are handled by the App Store. We never see your payment details.
Settings → “Erase everything & start over” wipes this device and overwrites your server backup with an empty one.
| Budget data you enter | Envelopes, amounts, transactions, challenges — to run the app and sync across your devices. Stored on-device and in your private Supabase record. |
| Account identifier | An anonymous device ID, or your Apple ID email if you Sign in with Apple — used only as the label your private data belongs to. |
| Purchases | Handled entirely by Apple’s App Store. We receive subscription status, never payment details. |
| Analytics / advertising | None. No third-party trackers, ad networks, or data brokers. |
Your data stays until you delete it. “Erase everything & start over” in Settings removes it from the device and replaces the server copy with an empty one. Deleting the app removes the local copy.
Stash is not directed to children under 13 and does not knowingly collect data from them.
If this policy changes, we’ll update this page and the “Last updated” date above.
