Option 1: in the app (instant)
- Open Presto and sign in, then open the menu and choose Parent settings (you'll be asked for your parent PIN).
- Scroll to the bottom to the Danger zone and tap Delete My Account.
- Confirm. The account is deleted straight away and can't be recovered.
The same steps work in the iPhone, Android and web versions. You can also delete just one run, all of a child's runs, or reset a
child's progress from the same screen, without deleting the account.
Option 2: ask us by email
If you can't sign in, have deleted the app, or would rather we do it, email us from the email address on your
account and we'll delete it for you.
Request account deletion
- Send it from the address you sign in with, so we can confirm the account is yours. If you send it from another address we'll reply
to check it's really you before we delete anything.
- We'll reply to confirm, and delete the account within 30 days (usually much sooner).
- You can also ask us to delete only some of the data, for example a problem report or a screenshot, and keep the account.
Delete some of your data, without deleting the account
- In the app (Parent settings, parent PIN required): delete a single practice run, delete all of one child's runs, or
reset a child's progress. The account and everything else stay.
- By email: ask us to delete particular data, such as a problem report, a screenshot you attached, or one child's profile, and keep
the rest. Use the same email link and tell us what to remove,
from the address on your account. We'll confirm, and do it within 30 days.
- You can also ask to see the data we hold about your family, or to correct it, at the same address.
What is deleted
Deleting an account permanently removes your login, every child's profile, practice history and progress, your settings
(including the weekly progress email addresses and parent PIN), and any problem reports and screenshots you sent.
What stays, and for how long
- Recovery copies, up to 7 days. Our database keeps a 7-day recovery window, so deleted data can still be restored from it
for up to 7 days before it disappears.
- Weekly backups, up to 8 weeks. We keep a weekly backup copy of the database for 8 weeks, so a deleted account's data is
gone from every backup within 8 weeks. If we ever restore from a backup, we delete again any account deleted after it was made.
- Our admin audit log keeps a record that an account was deleted, including its email address, so that changes to accounts are accountable.
- Problem-report tickets already created in our private issue tracker on GitHub (United States) stay there. They do not contain your email
address or your child's name. Email us and we will delete a ticket on request.
- Help questions a parent sent to our AI helper are not linked to your account. Our AI provider holds them for up to 30 days (longer if its safety systems flag them) and they cannot be deleted on request.
- Emails you sent us stay in our support mailbox until we delete them. Ask us and we will.
