Stacky is made by two people in Portugal. Email goes to one of them, and they answer it.
Get in touch
support@stacky-app.com for anything about the app — a bug, a question, a product that is wrong in the catalogue, an account you cannot get into.
privacy@stacky-app.com for anything about your data specifically: access, correction, erasure, or a question about the privacy policy.
We answer in English and Portuguese.
What to send
Write in whatever form you like. If something is broken, these four things usually save a round trip:
- The email address on your account, if you have one, so we can find it.
- What you expected to happen, and what happened instead.
- Where in the app it happened — the screen name is enough.
- Your iOS version and iPhone model, and whether you are on TestFlight or the App Store.
A screenshot covers most of it. If the app crashed, say roughly when; crash reports carry timestamps.
Deleting your account
You can delete your account from inside the app, without asking us: Profile → Settings → Delete account.
That is permanent and immediate. Your account and the health data attached to it (stack, intake history, mood entries, profile) are deleted, not hidden, and nothing remains for us to restore. If you might want your history later, export it first.
Deleting your Stacky account does not cancel an App Store subscription; Apple holds that. Cancel it separately.
If you cannot reach that screen, email support@stacky-app.com from the address on the account and we will delete it for you.
Getting your data out
The app exports everything it holds about your tracking: your stack, your intake history with the time of each tick, moods, the change log, your health profile and your subscription history. It arrives as a zip of CSVs plus one JSON file with the same rows.
Export any time, and before deleting an account.
Correcting a figure
Every intake figure on this site names the authority that published it and links to that authority’s own document. Those documents get revised, and we can transcribe one wrongly.
If a number is wrong, tell us at support@stacky-app.com and we will check it against the source and say what we found. How these pages are built explains where the figures come from and what is not published.
Subscriptions and refunds
Stacky Premium is billed by Apple, not by us, so we cannot see your payment details, change your plan or issue a refund.
- Manage or cancel: apps.apple.com/account/subscriptions, or on your iPhone under Settings → your name → Subscriptions.
- Refunds: reportaproblem.apple.com.
If Premium has not unlocked after a purchase, that is ours to fix: email us with the date of the purchase.
