Your account can be deleted right in the app in about a minute — together with all data. Here's how it works, plus a fallback method.
Settings → Account → "Delete account" → confirm. After confirmation the account and its data are deleted immediately and you're signed out.
Email support@pero.day from the address your account is registered to, with the subject "Account deletion". We'll delete the account within 30 days and confirm by reply.
Data leaves backups as they rotate: daily copies live 30 days, weekly ones 12 weeks, monthly copies and the cold archive about 12 months. Nothing deleted is kept anywhere beyond that. Deleted data cannot be recovered — if you need it, export first (in the app: Settings → Export data).
Deleting the account does not cancel the subscription — Apple manages it. Cancel it separately: iPhone Settings → your name → Subscriptions → Pero. Otherwise charges will continue.
