StampNamePrivacy Policy
StampName runs on your Mac. There is no account, no analytics and no tracking. The text of your documents never leaves your Mac.
Data Not Collected
We collect no data about your documents or your use of the app. StampName has no account registration, no sign-in, no telemetry or analytics, and no servers that receive your files. The only network requests the app makes are the license checks described below, and they never contain document content.
What Is Processed on Your Mac
StampName renames invoices and receipts based on what is printed on them. It reads the PDF and image files in the folders you choose, including text recognized from scanned pages. This processing happens only on your Mac. Document contents, extracted text and suggested names are never uploaded, shared, or sent to the developer or any third party.
What Is Stored Locally
StampName stores the following only on your Mac, inside the app's container:
- Undo journal: a record of the renames you have made, including each file's original and new path, its file identity and a hash, so a rename can be undone.
- Folder access: bookmarks for the folders you grant StampName access to.
- Settings and naming formats: your preferences and any naming formats you save.
- Remembered corrections: corrections you make for a particular sender, so StampName can apply them next time.
- Review draft: the in-progress state of a batch you are reviewing.
This data is not transmitted anywhere. You can delete it by removing StampName from your Mac or by using the data-clearing options in Settings. Standard Mac backups such as Time Machine may include app data; the developer has no access to those backups.
Your Files
StampName only accesses folders you explicitly grant. It renames files in place and does not overwrite existing files.
Purchases
StampName Pro (needed to rename files) is available as a yearly subscription or a one-time lifetime purchase from this website:
Polar acts as the merchant of record and handles payment and sales tax under its own privacy policy. We receive your email address, plan and order status from Polar so that we can issue and validate your license key. We never receive your card details. Your license key is emailed to you from license@stampname.app, sent through Cloudflare.
License Checks
StampName contacts our license server (a Cloudflare Worker) only to activate your license key and to check periodically that it is still valid. Each request contains the license key, a device identifier that is a one-way hash of your Mac's hardware ID combined with an app-specific value (the raw hardware ID never leaves your Mac), and a device name you can recognise, such as your Mac's name. It never contains document contents, file names or extracted text. If the server cannot be reached, Pro keeps working for up to 14 days from the last successful check.
Account Page
The account page at stampname.app/account lets you see your license. You enter your purchase email and we email a 6-digit sign-in code from license@stampname.app. The code is stored only as a hash, expires after 10 minutes and works once. After you enter it, our license server sets a single session cookie (HttpOnly, Secure, valid for 24 hours) that only keeps you signed in; it is removed when you sign out and is not used for tracking. The page shows your license key, plan, renewal date and the Macs activated (names you gave them, first activation and last check dates). Those details come from Polar and our license server.
This Website
Apart from the sign-in cookie described above, this website uses no cookies, analytics or tracking scripts and loads no third-party fonts or resources. Like any web host, the hosting provider (Cloudflare) processes standard request logs such as IP addresses to deliver and protect the site. When you choose Buy, your browser asks our license server for a checkout link and then goes to Polar's checkout page.
Third Parties
StampName contains no third-party analytics, advertising or tracking code. We do not sell or share personal data. The only third parties involved are Polar (payments) and Cloudflare (website, license server and license emails).
Children's Privacy
StampName does not collect personal data from anyone, including children under 13.
