Do you even have one?
Most people using Daybook have no Dhruvanta account at all, and don't need one. A Dhruvanta account only exists if you chose to sign in from the "Account" section of Settings in the Android app — it is entirely optional, and Daybook works identically whether you sign in or not. If you never saw or used that sign-in form, there is nothing for this page to delete, and no further reading is required. You can keep using Daybook, or delete your diary, without ever creating one.
Two different things, easy to mix up
Your diary lives entirely in a Google Sheet that you own, written to through a Google Apps Script Web App you deploy yourself. Dhruvanta never has a copy of it. There is nothing to request from us — you delete it the same way you'd delete any spreadsheet data: remove the rows, or delete the Sheet itself.
Your Dhruvanta account, and the encrypted copy of your Apps Script URL and API key it can optionally hold for restoring on a new device, is what this page is about.
Fastest option: remove the backup yourself
If you can still sign in on Android, open Settings > Account and tap Remove synced copy. That deletes the encrypted backup of your Apps Script URL and API key from Dhruvanta's server immediately — no email required, and you don't need to wait for a person to act on it. It's only available while signed in; signing out or uninstalling the app does not remove it, which is exactly why this button exists.
That removes the backup, not the account itself. If you're done with Daybook entirely and want the account gone too, use the request below.
Requesting account deletion
There is currently no self-service way to delete a Dhruvanta account outright. To request it, email jayashankar.pjs@gmail.com from the address you can be reached at, and include the email address you signed in with. A person — not an automated system — will read the request and act on it, so it is not instant.
This deletes the account and any encrypted Apps Script credential backup associated with it. Beyond that, we can't honestly give you a general-purpose retention policy here, because there is no automated process to describe one for — every request is looked at and answered individually, and we'll tell you plainly what was done.
This never touches a diary kept in your own Google Sheet: your Sheet and Apps Script deployment are yours, live in your own Google account, and are unaffected by anything done here. A diary kept in Dhruvanta cloud is separate, and deleting your Dhruvanta account does not delete it. To erase it, sign in and use Delete everything in Settings (it appears there if you have a cloud diary).
