Pro and licence

Free and Pro

The base app is free, with no time limit and no account. Free on every platform:

• day notes with the complete syntax, writing, formatting, sections and links;
• today's tasks and appointments, and the overdue tasks in the task list;
• ticking off, moving and dropping tasks, repeating tasks and appointments;
• the Day view of the calendar;
• the full-text search, and the Mentions in the overview of a tag or person;
• the revision history and the ZIP export;
• a simple home-screen widget on Android, showing today's tasks;
• switching between profiles that already exist;
• syncing your notes folder with a program of your own, such as Syncthing or the Nextcloud app.

tagwerk Pro adds the following. The middle column says what you see without it.

Locked controls stay visible. Pressed, they open a card headed Part of tagwerk Pro that names the feature, with Buy Pro where the platform sells it.

Price

Pro costs €12 / US$12, once. There is no subscription and no expiry date. One purchase covers all your devices and platforms, and every profile on each device.

On Android from Google Play, the tagwerk Pro section shows the price Google Play reports for your account (One-time purchase: and the price).

On Linux every Pro feature is included. There is nothing to buy. The Linux app has no reminders.

Getting Pro

Every Android and Windows build accepts a licence file, whichever way it was bought.

Android from Google Play

1. Open Settings → tagwerk Pro and press Buy Pro.
2. Google Play shows its own purchase dialog. If the purchase does not go through, the reason is in that dialog.
3. Once Google Play confirms the payment, Pro is unlocked on this device. The section then says Pro is active - bought through Google Play.

If the payment is not confirmed yet, the section says The payment is not confirmed yet. Pro unlocks by itself once Google Play confirms it. Check again asks Google Play once more.

On a new phone or after a reinstall, sign in with the same Google account and press Restore purchase. If Google Play has no purchase for that account, the app says No purchase found for the Google account on this device.

The purchase belongs to your Google account. To use Pro on a device without it, turn it into a licence file: see Pro on your other devices.

Android without Google and Windows

1. Open Settings → tagwerk Pro and press Buy Pro. The licence page opens in your browser.
2. Pay there. The checkout is Stripe's and asks for a name for the licence and an e-mail address.
3. The licence arrives by e-mail, usually within a minute. Nothing in the app changes until you activate it.
4. Activate it in one of two ways:
   • Paste the block from the mail into the field under Import licence and press Import licence. The app says The licence was imported.
   • Save the block as a file named tagwerk.license in the settings folder of your notes folder. Then your folder sync carries it to your other devices too. tagwerk reads the file when it starts, so close and reopen the app.

The section then says Pro is active - licensed to and your name.

No mail after a few minutes? Look in the spam folder, then use the form under Licence lost? on the licence page.

Linux

Every Pro feature is included on Linux, for good. The settings have no tagwerk Pro section, and no licence is needed.

The licence file

A licence is a small signed text file, tagwerk.license. tagwerk keeps it in your notes folder:

Tagwerk/
|- 2026/
|- templates/
`- settings/
   `- tagwerk.license

A file named tagwerk.license at the top of the notes folder is found too.

• It holds your name, your e-mail address, the purchase date and an order number. It has no expiry date.
• It is checked on the device, offline. tagwerk asks no server whether you may use it.
• Do not edit it. A changed file no longer passes the check.
• With several profiles, Pro holds for every profile on this device, even if only one profile's notes folder has the file.

Because the file lies in the notes folder, whatever carries your notes carries the licence.

Pro on your other devices

Three ways bring an existing licence to another device:

1. Your own folder sync. Syncthing, the Nextcloud app or a desktop sync client copy settings/tagwerk.license like any other file. Once it has arrived, close and reopen tagwerk on that device: the file is read at the start.
2. The built-in sync. It uploads the licence only when the server has none, and downloads it only when this device has none; a downloaded licence counts at once. It never replaces and never deletes a licence. The built-in sync itself needs Pro, so it helps a device that is already Pro, such as a phone with a Google Play purchase. Details in Sync.
3. Copy and paste. On a device with the licence, Settings → tagwerk Pro shows Your licence with the text of the licence. Press Copy licence, bring the text to the other device, and paste it there under Import licence. If the clipboard is refused, the text is selected and can be copied by hand.

From a Google Play purchase

A Google Play purchase unlocks only the phones signed in to that Google account. To get a licence file from it:

1. Open Settings → tagwerk Pro on the phone with the purchase.
2. Optionally, fill in Name for the licence and E-mail for recovery (optional). Google does not pass on who bought, so the licence contains what you enter here. The address is only stored to send you the licence again if you lose it.
3. Press Use Pro on your other devices. tagwerk fetches the licence and writes it into your notes folder: The licence file is in your notes folder.
4. Carry it on with one of the three ways above.

If the licence server cannot be reached, the app says The licence server could not be reached. Try again later.

When Pro is missing

Without Pro, the Pro features show what the table in Free and Pro says. Nothing is deleted: template files, tag colours, widget configurations, sync settings and profiles stay where they are, and take effect again as soon as Pro is back. Your notes are never behind Pro.

If the notes folder cannot be read for a moment - a network drive away, a file locked by a sync client - Pro stays as it was.

If a licence file is there but does not pass the check, the tagwerk Pro section says A licence file is in the notes folder, but it could not be verified and adds why in a sentence, for example The text is incomplete or not a licence. Usually the file was changed or only partly copied. Paste the licence from the mail again under Import licence. If that does not help, see Troubleshooting.

Removing a licence

Settings → tagwerk Pro → Remove licence switches Pro off on this device and removes the licence file from this notes folder. It is offered where a licence file is what unlocks the device, for example before handing a computer on. Nothing is cancelled, and you can paste the licence back at any time.

A Google Play purchase cannot be removed in the app.

A lost licence

• Bought through Google Play: press Restore purchase on a phone with the same Google account.
• Another device still has it: copy it there under Your licence and import it, see Pro on your other devices.
• The purchase mail is still there: paste the block under Import licence.
• Nothing of the above: on Windows and Android without Google, Licence lost? in Settings → tagwerk Pro opens the form on the licence page. Enter the address you bought with. The licence is only ever sent to the address stored with the purchase.

A licence fetched with Use Pro on your other devices can only be sent again if an address was entered under E-mail for recovery (optional).

If none of this works - a licence that will not take, a purchase that never arrived - the licence page says how to reach us. Mention your platform and the version from the bottom of the settings page.
