Deleting your data
Last updated 7 November 2026
Draft. This page has not been checked by a lawyer yet and is not legal advice. Still waiting for counsel: the time we promise for answering a request in each launch country, and how a parent's request is handled under the rules for children.
Melisol has no accounts, so there is no account to delete. What you sing never leaves your phone. A few things do leave it when you send them or say Yes, such as a challenge's scores or a message (see the Privacy Policy), and this page says how each one is deleted.
In the app, at once
- A conversation in Messages: open Messages and tap Delete this conversation. It is deleted from Melisol's server at once, with the developer's replies.
- Anonymous counts: turn off "Send anonymous counts" in Settings. Nothing more is sent, and the counts still waiting on your phone are deleted. Counts already sent were added to totals with no code for your phone, so they cannot be told apart from anyone else's.
- The iCloud copy (iPhone): turn off "iCloud copy" in Settings, Progress. The copy in your iCloud is deleted, and no new one is saved. Do this before you delete Melisol: deleting the app does not delete the iCloud copy.
- Everything on your phone: delete Melisol. That removes its files, its settings and the random codes it kept for challenges, Messages and reports; installing it again starts fresh. Your iCloud or Android backup keeps its own copy until you delete that backup in your phone's settings.
By request, with your conversation code
If you no longer have the app or the phone, write to support@melisol.app with the conversation code Messages showed you (8 letters and digits, in two groups of four, such as K7M2 Q9X4). We delete that conversation and all its messages, and write back when it is done.
We answer within one month.
The code is the only way we can find a conversation, because Melisol never knows who you are. Anyone who has the code can ask, so keep it to yourself.
Deleted on its own
Everything below is deleted automatically, within a day of its time. Challenges, reports and practice sets carry only random codes, never a name, and we cannot tell which phone sent them, so we cannot find them from a request. A conversation can also be deleted at once, as above.
| What | Deleted |
|---|---|
| Challenges and their scores | 14 days after the challenge was made |
| "Something sounds wrong" reports | After 90 days |
| Shared practice sets | 12 months after anyone last opened them in Melisol |
| Conversations in Messages | 12 months after the last message |
| Totals of anonymous counts and daily crowds | After 25 months (counts) and 13 months (daily crowds) |
| Crash and error reports (kept by Sentry, not on Melisol's server) | After 30 days |
After anything is deleted, it can stay in the server's own database backups for up to 30 days before it is gone for good.
Purchases
Your purchase records are kept by Apple or Google, and by RevenueCat under a random id, with the phone details the Privacy Policy lists. To ask for RevenueCat's record to be deleted, write to us with the order number from the store's receipt email, and we will ask RevenueCat to delete it. Apple's and Google's own records follow their policies.
