The short version

Roger is built and run by one person — a ham radio operator, not a company. It is free, has no ads, and never sells or shares your information for advertising. Everything below exists to run the app itself: keeping your practice progress, letting you get it back if you switch devices, and showing you your own stats.

What Roger collects

Most of what Roger stores about you, you never had to type in.

• An operator handle. Every install is assigned a random handle (like QRZ-4821) automatically, so your progress can be saved without asking for anything. This happens whether or not you ever provide an email.
• Practice history. Which articles you've copied, your accuracy, characters and words copied, timing, and which letters trip you up — this is what drives your reports, streaks, and badges. It's tied to your handle, not to you as a real-world person.
• A device credential. A random per-device key that proves a sync request is really from your device. It isn't personally identifying on its own.

If you choose to "sign up" in Settings, Roger additionally asks for:

• An email address — used only to send you a one-time recovery code if you reinstall or switch devices, and to email you a certificate image when you earn one.
• A username or call sign (optional, shown on the public leaderboard if you set one) — you choose what this says; a call sign is public information you're opting to display, and a made-up handle works just as well.

If you use the feedback form in Settings, the message you write is sent to the operator's inbox, along with your handle and email if you have one on file (so a reply is possible) — anonymous feedback works too.

What Roger never touches

The Android app requests exactly two permissions: internet access and network state — both needed just to talk to Roger's own server. That's the entire list.

Where it lives, and who else sees it

Your data is stored in Turso (a hosted database) behind a Cloudflare Worker that only Roger's own app talks to. The one outside service involved is Resend, used solely to deliver the emails described above (recovery codes, certificates, feedback) — your email address and, for feedback, its message text pass through Resend for that purpose only.

Your IP address is used briefly to limit how many recovery-code guesses or feedback submissions can come from one source in a short window — a simple counter that resets on its own, not a stored history of your activity.

Your choices

• Skip the email entirely. Roger works fully anonymously under your auto-assigned handle — signing up is only needed if you want your progress recoverable on a new device.
• Multiple devices. Signing in on a new device doesn't silently sign out an old one — Roger asks which one should keep the account.
• Delete your data. Email roger@k5grr.com with your handle or the email on file, and your account and practice history will be deleted.

Changes to this policy

If what Roger collects ever changes in a meaningful way, this page will be updated and the effective date above will change. There's no mailing list or push notification for policy updates — check back here if you're curious.
