Collaborative notes
Collaborative notes, shared in real time.
Your keys stay sealed — even from us
Private by design,
Private by design,
not by promise.
TensorActivity builds apps for notes, files and documents. The account behind them holds your keys sealed — built so it can’t read them, not merely told not to.
One account for our connected apps. Delete it whenever you like — it’s gone the moment you do.
You’re signed in. Manage or delete your account any time — deleting takes one click.
Apps
Made by TensorActivity
Some use your TensorActivity account. Some don’t need one at all — everything stays on your device.
Atlaswave
Encrypted storage
End-to-end encrypted storage, with Atlaswave Photos alongside it.
Coming later
Veltax
Private vault
A private vault for your photos, videos and notes that lives on your device. No account, no cloud sync.
OnePDF
PDF editor
Read, edit, annotate and fill PDFs entirely on your device. No account and no uploads.
How the account is built
An account that holds less.
The strongest privacy promise is one nobody has to keep. So the account is built to need, and hold, as little as possible.
Your keys arrive sealed
Key material is encrypted on your device before it reaches us. We keep the ciphertext and nothing that opens it — so even a complete copy of our database decrypts nothing.
Tokens that expire in minutes
Access tokens last fifteen minutes. One that leaks is worth minutes to whoever holds it, not days.
Delete means gone
Delete your account and your sign-in, devices, memberships and stored keys are removed on the spot. No 30-day wait.
Apps never see your password
You sign in on TensorActivity’s own page. Apps receive a short-lived token, never the password itself.
Length over silly rules
Ten characters and no forced symbols, because a long passphrase beats a short scramble.
One account for everything that needs one.
Your account, whenever you need it.
Create it once, use it across our connected apps, and delete it whenever you like.
Devices, apps and deletion all live in one place.
