Short version: the iPhone app collects nothing at all. The Mac app sends one small anonymous note a day, which you can switch off in one click. Problem reports only go anywhere when you write one and press Send. Nothing is ever sold, and there are no accounts, no ad networks, and no third-party trackers inside either app.
MarkeMark is made by one person, Adam Raabe. If anything below is unclear, email hi@markemark.app and ask.
MarkeMark for iPhone
The iPhone app collects nothing. It has no analytics, no accounts, no advertising, and no network code of its own. It reads the file you tap, renders it on your phone, and that is the whole story. Your documents never leave your device. Apple's privacy label for this app reads "Data Not Collected", and that is literal.
While the app is in beta it is distributed through Apple's TestFlight. TestFlight is Apple's, not mine, and it does two things I do not control: it collects crash logs from beta builds, and it lets you send feedback and screenshots to me if you choose to. If you send TestFlight feedback, I see what you wrote, the screenshot you attached, and the device and iOS version it came from. Crash reports reach me the same way. Apple's own privacy policy covers TestFlight itself. Nothing about this changes when the app leaves beta, except that the beta crash reporting stops.
MarkeMark for Mac
There are exactly three times the Mac app talks to a server.
1. The daily hello. Once a day the app sends a small anonymous note so I can tell whether anyone is using it: a random ID created on your Mac, the app version, your macOS major version, and counts of how often you opened a document, switched view modes, exported, printed, or used Quick Look. That is the complete list. It never sends your documents, file names, folder names, paths, or anything you search for, and the random ID is not tied to you, your Mac's hardware, or any account. Help → Privacy & Data shows the same list inside the app and has one switch that turns it off. Off means nothing is sent at all.
2. Problem reports. Nothing is sent unless you open Help → Report a Problem, write something, and press Send. What goes with it: what you wrote, and your app version and macOS version. Your email address goes too, but only if you type one in because you want a reply. The diagnostics log and a fragment of the document you were working on are attached only if you tick those boxes yourself, per report. Problem reports use a separate random ID from the daily hello, on purpose, so the two cannot be joined up.
3. The update check. Once a day the app asks markemark.app whether a newer version exists. The request carries the app version and nothing else.
All three are ordinary web requests, so my server sees what any web server sees: an IP address and a timestamp. Those logs are not used to build a profile of anyone, and they are not joined to anything else.
This website
markemark.app uses Cloudflare Web Analytics, Vercel Analytics and Speed Insights, and PostHog to count visits and see which pages people read. PostHog sets a cookie in your browser; the other two do not. None of it is advertising, and none of it is shared with anyone.
If you join the mailing list, I keep your email address so I can tell you when a new version ships. Every one of those emails has an unsubscribe link, and unsubscribing deletes the address.
If you email me, that email sits in my mailbox like any other email. I do not add you to a list because you wrote to me.
What never happens
- Nothing is sold or rented to anyone, ever.
- No advertising networks, no ad IDs, no cross-site tracking.
- No accounts, so there is nothing to breach.
- Your documents are never uploaded, scanned, indexed, or read by me or by any service.
Children
MarkeMark is not aimed at children and does not knowingly collect anything from anyone under 13.
Changes
If this ever changes, I will update this page and say so in the changelog. Questions, corrections, or a request to delete something: hi@markemark.app.
