yours alone
Private by design, not by promise.
Most apps ask you to trust them with your data. oh deary never gets it in the first place.
Encrypted on your phone
Every entry, photo, mood and tag is encrypted before it’s stored, with a key only your password or recovery key can unlock.
No account, no servers of ours
You don’t sign up for anything. There is no oh deary server that could be hacked, sold or shut down with your diary on it.
No ads, no tracking
No ads, no analytics, no tracking SDKs. The app doesn’t send anything anywhere unless you turn on backup.
Nobody can read it, not even us
Not even we can open your diary or reset your password. That’s the point. Your recovery key is the spare key, and only you have it.
AES-256-GCM encryption · Argon2id password keys · biometric unlock · auto-lock · screenshots blocked

What Google can see. And what we can’t promise.
Privacy claims are easy to make. Here’s exactly where ours end.
- With backup on
- Google stores only encrypted files. It can see how many there are, how big they are and when they change, so it can tell when you write, never what.
- Without backup
- Your diary exists only on your phone. Lose the phone, lose the diary. Android’s own backup is switched off for oh deary on purpose.
- A forgotten password
- Nobody can reset it for you. Your recovery key is the only way back in.
- A hacked phone
- Encryption can’t protect your diary on a hacked or rooted phone while it’s unlocked.
- Exports
- A CSV export isn’t encrypted: anyone with the file can read it.
questions
Good to know
What if I forget my password?
When you create your diary, oh deary gives you a recovery key. With it you can open your diary and set a new password. Keep it somewhere safe: without your password or recovery key, nobody can open the diary, not even us.
What if I lose my phone?
Your diary is stored only on your phone, so without a backup it’s gone with the phone. With Premium, oh deary keeps an encrypted copy in your own Google Drive, and you can restore it on a new phone with your password or recovery key.
Can Google read my diary?
No. Google only stores encrypted files it can’t read. It can see how many files there are, how big they are and when they change, so it can tell when you write, but not what. oh deary only asks for access to its own hidden app folder, so it can’t see any of your other Drive files.
Is there an iPhone version?
Not yet. oh deary is available for Android phones and tablets (Android 11 and newer).
Can I use it on more than one phone?
Yes, with Premium. Your devices sync through your own Google Drive, and if two of them change the same entry, nothing gets lost: you’ll see both versions.
Can I get my entries out?
Yes. With Premium you can export all entries as a CSV file. Note that this file isn’t encrypted: anyone who has it can read it.
Why a one-time price instead of a subscription?
Because there are no servers to pay for. Your diary lives on your phone and, if you like, in your own Google Drive. So you pay once, and it’s yours. No subscription, no ads, no upsells.
