1Who we are
papergrinder (papergrinder.com) decides how your data is used. For any question or request, email hello@papergrinder.com.
2What we collect
- Without an account: your practice stays in your browser. We receive your searches, any photos you upload, and basic request details like your IP address.
- Your account: your email address, and your name and picture if you sign in with Google. With an email code, your name starts as the part of your email before the @. You can change it in Settings.
- Your practice: what you type, draw and photograph, and your marks, collections and progress.
- Devices: the kind of device and browser you sign in on, when each was last used, your IP address, and a random id for each browser, kept for 30 days after last use.
- Payments: your plan and its dates. Card details go to our payment provider and never reach us.
- Referrals: your link code, and whose shared link brought you to papergrinder.
- Messages: what you send from Contact us or Report, with any attachments, the page you were on, and your email if you leave one.
- Usage statistics: how papergrinder is used. To opt out, email us.

6Where it is stored
Your data is stored in the EU and encrypted when stored. Some providers process data in other countries under approved transfer terms.
7How long we keep it

8Your rights
You can ask to see, correct, download or delete your data, or object to how it's used. Email hello@papergrinder.com from your account's email address. Deleting your account deletes your data. We reply within a week. You can also complain to the Information Commissioner's Office at ico.org.uk.
9Browser storage
Your browser's storage keeps you signed in, holds your practice and settings on this device, and keeps a random id for usage statistics.
Signing out clears your practice from the browser but keeps your settings and any changes not yet saved. Practice done without an account joins the next account that signs in on that browser, so clear the site data when you finish on a shared computer.
10Children
You must be 13 or over to make an account. Keep names and faces out of photos of your work. We aren't responsible for personal details you include in uploads.
