Hyperfocus is not your problem.
It is your SUPERPOWER.

No. There is no account, no password and nothing to sign into — HYPER opens straight into the void. The only sign-in anywhere in the app is Spotify's own, if you choose to connect your music, and that happens on Spotify's page. HYPER never sees your password.

Everything you make — every session, every project, every thought you set down — lives on your device and nowhere else. There is no account and no server. HYPER has never held a copy of any of it.

No analytics SDK, no advertising identifier, no behavioural tracker of any kind. Nothing you write is transmitted anywhere by HYPER — not for backup, not for improvement, not for training anything. It also shows you no one live: no count of who is working right now, nobody to see and nobody who can see you — producing one would mean your phone reporting in, and it never does. What the globe carries instead is a quarterly, dated count of downloads by country, read once per launch from the same small public file every phone asks for; that request sends nothing.

Two crash-shaped things worth naming because they are easy to miss. If HYPER itself crashes, it sends one report so the bug can be fixed — the stack trace, the phone model, OS and app version, and which screen was open. It never contains anything you wrote, file paths are stripped before it leaves, and it is processed by Sentry with no identity to link to, because HYPER has none. Separately, if your phone shares crash diagnostics with Apple or Google, the crash can also appear in the store's own developer console — that part is your phone's setting.

That is the privacy, and this is its whole cost, said plainly rather than buried: HYPER cannot bring your Vault back, and nobody can. Not because we won't — because it was never ours to hold.

So HYPER makes the copies for you. After you leave the app it quietly writes your whole Vault into its own storage, where your phone's own backup carries it off the device — as long as you have that switched on. One row in Settings → Safekeeping saves that same Vault as a single file you keep wherever you like: Files, a drive, an email to yourself. The row beneath it puts everything back from that file. And you can point HYPER at a folder you own — in iCloud Drive, Google Drive, anywhere your files app reaches — where fresh copies then land on their own: on Android without you, on iPhone the next time you open the app. Off the phone either way, out of reach of anything that happens to it. The next two answers are exact about how far each of those goes.

Yes — and here is exactly how far that reaches, because a promise bigger than the truth would be worse than no promise at all.

After you leave the app — never during a session — HYPER quietly writes a copy of your whole Vault into its own storage, at most once every six hours, keeping the last five. It reads each one back off the disk to be sure it would actually restore. Those copies sit where your phone's own backup can carry them off the device — so, as long as that backup is switched on, they survive replacing the phone, removing the app and putting it back, and a phone that dies.

What they do not survive: they live inside HYPER's own container on the phone. Clear storage deletes them in the same tap that deletes the Vault, and with your phone's backup — iCloud Backup, or Google One on Android — switched off, none of the three cases above survives either: the copies never leave the phone, so they go wherever it goes. There is nowhere on the phone HYPER can write to by itself that survives that button.

Which is why the copy you keep somewhere else is the one that matters.

One file, kept anywhere but this phone, and there is a way back from every ordinary way a Vault actually goes. Losing the phone is not the likeliest of them: uninstalling HYPER, tapping Clear storage in your phone's app settings, or setting up a new phone and skipping this one's app data each empty it just as completely, and all three are ordinary taps, usually taken while freeing up space. A backup file brings everything back — it is the only thing that can, and writing one takes seconds. Here is how to keep a good one.

Write one. Settings → Safekeeping → save a backup. HYPER writes a single file with your whole Vault inside it and hands it to your phone to put somewhere: Files, a drive, an email to yourself. Where it lives after that, and whether it is still there in a year, is yours.

Keep it off this phone. A copy that exists only on the phone it came from dies with the phone.

Better still, point HYPER at a folder you own — in iCloud Drive, Google Drive, anywhere your files app reaches — and copies land there on their own. That is the copy that survives Clear storage, because it isn't on the phone. On Android the folder stays chosen; on iOS your phone lends it only while the app is open, so the first copy after you come back takes one tap to confirm. HYPER keeps the last five it wrote there, removes its own older ones, and never touches anything else in that folder.

Write a fresh one after any stretch of work you'd hate to redo. A backup is a photograph of a moment, not a live mirror — it holds what existed when you made it, and nothing after.

Know what restoring does. Restoring replaces what is on the phone with what is in the file. It does not merge the two. HYPER shows you both columns first — what is in the file, what is on this device — and the last step is a hold rather than a tap, because it cannot be undone.

Keep the file as private as the work. Everything you wrote is legible inside it. It never travels to us; it goes wherever you send it.

And the part only you can do: we cannot recover a backup you have lost, repair one that is damaged, or produce one that was never made.

Save a backup on the old phone and put the file somewhere both phones can reach. Install HYPER on the new one, then Settings → Safekeeping → restore from a backup. Everything arrives: sessions, projects, thoughts, the Brain, the Vault.

Then write a fresh backup from the new phone. HYPER treats a restored Vault as one that has never been copied yet — and it is right to: the file you restored from is already ageing on the old phone's timeline. Being asked again is the correct answer, not an alarm.

Write a backup file first and you can delete freely: it holds the whole Vault, and restoring it later puts all of it back. Without one, deleting HYPER takes the Vault with it — there is no account to close, nothing left on a server, and no one to tell. Deleting is the erasure, and the backup file is the export.

If your phone's own backup is switched on it may carry HYPER's latest copy across a reinstall, but that is your phone's promise rather than ours. The file is the one that is entirely yours.

The whole of both documents, in plain words, lives on the privacy page and inside the app under Settings → Privacy & terms.
