What leaves your Mac, and who gets it

Your notes
Nobody. Papr uploads nothing.
The free trial
Us: when Papr opens during the trial, a one-way hash of your Mac’s hardware ID, to check when the trial began. Nothing else.
Polar
When you buy: your payment details, which Polar handles, and your email and order details. When you activate and about once a day after: your license key, your Mac’s name and a one-way hash of its hardware ID.
GitHub
Update checks and downloads come from GitHub. Nothing about you or your notes is sent.
Us
Your email and order details, which Polar passes to us to provide your license and support.

Your notes

Each note is a Markdown file in Documents › Papr, one folder per collection, with its images next to it, saved after every change. You can open, edit or back them up with any app.

Papr uploads nothing. If your Documents folder syncs with iCloud, your notes sync with it, through iCloud and not through Papr. There is no account and no analytics.

Free trial

To count the trial’s 14 days, Papr keeps the day it began on your Mac: in its data folder (Library › Application Support › Papr) and in your Keychain. When Papr opens during the trial, it also sends a one-way hash of your Mac’s hardware ID to our trial server, which keeps only that hash and the day it first saw it, so the trial starts once per Mac. Nothing else is sent, the hardware ID itself never leaves your Mac, and no key or account is needed.

License checks

Activating sends your license key, your Mac’s name and a one-way hash of its hardware ID to Polar’s license API. Papr re-checks about once a day. The hardware ID itself never leaves your Mac.

Updates

Update checks and downloads come from GitHub, where Papr’s releases are published. Nothing about you or your notes is sent.

Purchases

Polar is the merchant of record: it sells Papr to you, takes the payment and issues your license key. Polar handles your payment details. We receive your email and order details from Polar to provide your license and support.
