Penline keeps everything you'd otherwise scatter across four apps — written down, organised and end-to-end encrypted. Not even we can read it.
On a tablet it opens out into three panes — your folders, your list, and the note you're working on, side by side. On a phone it folds back to one. Write on one device, pick it up on another.
iPhone · one paneMost people keep notes in one app, tasks in another, receipts in a folder and PDFs wherever they land. Penline holds all four, and they know about each other.
Rich text, photos, tables, checklists and drawings, organised in nested folders and tags.
A clear list for today, a calendar for the month, and boards for bigger projects. Reminders arrive when you asked.
Multi-currency, with the rate locked at the moment you spent. Scan a receipt and it fills itself in.
Ink, highlight, underline, strike and arrows. Your markup syncs to your other devices, encrypted like everything else.
Instead of four apps that never talk, everything about the thing you're working on lives in one place.
Most apps promise not to look. Penline is arranged so that looking isn't possible. What reaches our servers is unreadable — to us, to anyone who compelled us, and to anyone who stole the database.
Notes, tasks, expenses, attachments and PDF markup. Encrypted before upload, decrypted only on your devices.
A recovery key you keep, or approval from a device you already trust. No backdoor, because there isn't one to have.
New phones and tablets join only when one of yours says yes. Nobody can quietly add a device to your account.
Export everything you've written, any time, on every plan. Data ownership isn't a paid feature.
The free plan isn't a trial — it's the whole app for one person, with no caps on how much you write.
Encryption, sync and recovery are never paid features.
Right. Everything is encrypted on your device before it's uploaded, using keys only your devices hold. Our servers store ciphertext, so there's nothing readable to look at, hand over, or leak.
Use your recovery key, or approve the new device from another device you already trust. Because there's no backdoor, keep your recovery key somewhere safe.
No. Standard is the whole app for one person, with no caps on how much you write. Pro adds templates, budgets and insights, PDF annotation, unlimited scanning and 100 GB of storage.
Yes. You can export everything you've written, any time, on every plan.
