Privacy
SpreadPaper collects nothing
No account, no sign-in, no analytics, no telemetry, no crash reporting. There is no server of ours for your data to sit on. Everything below is the detail behind that sentence.

Your images never leave your Mac
The photograph you pick is opened, cropped and rendered on your own machine, and the result is written to your own disk. It is never uploaded anywhere. The app runs inside Apple's sandbox and can only read the files you hand it through the open panel or by dragging them in.
Your presets, schedules and display arrangement are stored locally in the app's own container, alongside the rendered wallpapers. Deleting the app removes them.
The one thing the app does over the network
SpreadPaper checks whether a newer version exists. To do that it asks GitHub's public API about this project's latest release, and fetches the changelog file from the repository. Nothing about you is sent. The request carries what any HTTP request carries: your IP address, and a user agent naming the app and its version, for exampleSpreadPaper/1.10.0.
That request goes to GitHub, not to us. We never see it, and we keep no record of who checked or when. GitHub's handling of it falls undertheir privacy statement. If you would rather it did not happen at all, the update check is the only outbound request in the app, and blockingapi.github.com stops it.
This website
spreadpaper.app is a static site with no analytics, no tracking pixels and no cookies of its own. It is served by Cloudflare, which keeps standard request logs for security and abuse prevention undertheir privacy policy.
The page loads its typeface from Google Fonts, which means Google receives your IP address when you visit. That is the only third party the page contacts. Downloads are hosted on GitHub, so following a download link takes you to them.
If you get in touch
Email sent tohello@spreadpaper.app is forwarded to a personal mailbox and kept only as long as the conversation is useful. Anything you post as a GitHub issue is public, and governed by GitHub's terms rather than this policy.
Your rights
Under the GDPR you may ask what personal data is held about you, and ask for it to be corrected or erased. In practice there is nothing to hand over unless you have emailed, because nothing is collected. The project is run from the Netherlands by Robin van Baalen. Ask athello@spreadpaper.app.
Changes
If this policy changes, the date at the top changes with it. The app is open source, so you do not have to take any of the above on trust: the update check lives inUpdateChecker.swift, and it is the only place the app opens a connection.
