Privacy Notice

The Website

Cloudflare hosts this site and the Mac download. Nothing is sold.

On a phone, where birdflow can't run, the site can email you the download. We keep your email address, when we sent it, whether you asked for the one reminder, and which ad brought you. Resend, in the United States, sends the email. Nothing else is ever sent to you. Write to hello@birdflow.app to be removed.

To measure our ads on Facebook and Instagram, the site runs the Meta Pixel. It tells Meta which pages you open, whether you click Download and whether you ask for the trial email, though never your address, with your browser's details and Meta's cookies, so Meta can match the visit to an ad you saw. Meta handles this under its own Privacy Policy.

To see how the site is used, it also sends PostHog, in the United States, the pages you open, how far you scroll, where you click, and a recording of the visit with anything typed hidden. It sets no cookie and forgets the visit when you close the tab. If your browser asks sites not to track you, it sends nothing.

The App

Your photos stay on your computer, and there is no account. To help improve birdflow, the app sends crash reports and anonymous usage data: its version, your computer model and operating system, and how the app is used, including screen recordings with everything on screen hidden. They go to PostHog, stored in the United States. Tick Don't Send in the app's introduction and nothing is sent. Your photos, file names, folders, locations and species are never sent. Otherwise the app goes online only for setup, maps, place names, licence activation and updates, listed in the FAQ.

On Windows, birdflow comes from the Microsoft Store, which installs and updates it under Microsoft's own privacy statement.

Buying birdflow goes through Polar, our merchant of record. Polar handles the payment and keeps your email and receipt. Entering or removing a licence key sends the key, your computer's name and the app version to Polar.

Send Feedback

Only when you press Send in the app's feedback dialog, we receive your message, a reply email if you gave one, the app's version and your system's details, which screen you were on, and recent error messages with file names, folders and quoted values removed. Ticking Include Screenshot also sends a screenshot. It's stored as a private issue on GitHub, Inc. (United States) and in Cloudflare.
