Your notes, tasks and spending. In one place.

Penline keeps everything you'd otherwise scatter across four apps — written down, organised and end-to-end encrypted. Not even we can read it.

Notes

Every device you own

iPhone, iPad, Android phone and Android tablet

The same app everywhere, with the same encrypted data behind it. On a tablet it opens out into two panes — your list on the left, what you're working on beside it — and on a phone it folds back down to one. Write on one device, pick it up on another.

One app

Four things you already do, stitched together

Most 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.

Notes

Rich text, tables, checklists and drawings. Nested folders, full-text search, and templates to start from.

Tasks

Today, upcoming, and boards for bigger projects. Reminders that arrive when you asked, with subtasks and priorities.

Expenses

Multi-currency with the rate locked at the time you spent. Scan a receipt and it fills itself in. Split costs with a group.

PDFs

Open, read and mark up any PDF. Your highlights and handwriting sync to your other devices, encrypted like everything else.

Private by design

We built it so we couldn't read your notes

Most apps promise not to look. Penline is arranged so that looking isn't possible. Everything is encrypted on your device before it leaves, with keys only your devices hold. What reaches our servers is unreadable — to us, to anyone who compelled us, and to anyone who stole the database.

End-to-end encrypted

Notes, tasks, expenses, attachments and PDF markup. Encrypted before upload, decrypted only on your devices.

Yours to take away

Export everything you've written, any time, on every plan. Data ownership isn't a paid feature.

Sync you can trust

Every device stays current without the server ever seeing plaintext. Sharing a note keeps it encrypted end to end.

Recovery that's really yours

A recovery key you keep, or approval from a device you already trust. No backdoor, because there isn't one to have.

Pricing

Free to use properly. Pro when you want more.

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.
