DeckFlex shows Magic: The Gathering Commander decks on a virtual table, lets playgroups ("pods") record their games and statistics, and has a shared life counter. This page says what it keeps about you, who can see it, who else is involved, and how to download or delete it. In short: no ads, no analytics, no tracking, and nothing is sold. It keeps what you put into it so the app can show it back to you and your playgroups.
| What | Why | Who can see it |
|---|---|---|
| Your sign-in: the Google account you sign in with (an account id, your name and email address, held by Google Firebase Authentication) | To know which decks and games are yours | Not shown to anyone. Your email is never shown in the app. |
| Your public profile: public name (your Google name unless you change it), optional username, optional playmat image link | So friends and pods see who you are | Anyone with your profile link, a pod link you are in, or your username |
| Your decks and collections: names, commanders, decklist links, sleeves, brackets, layout | The point of the app | Anyone with your profile link (profiles are unlisted: nobody can browse a list of users) |
| Friends: the people you added | Quick access to their decks | Only you |
| Pods and games: pods you are in; for each game, who played, with which deck, the result, knockouts and anything recorded about it, and the answers each player gives afterwards (fun, salt, bracket fit, props, a highlight, why they didn't win) | Game history and statistics for your playgroup | Anyone with that pod's link. Your answers are stored with your account. |
| Shared life counters: the life totals and changes of a game in progress, which seats are being played on which device, how many devices are connected | So every device at the table sees the same game live | Anyone with that game's link or QR code, while the game lasts. It is deleted when the game ends. |
A device that opens a shared life counter without being signed in gets an anonymous sign-in: a random id with no name or email, used only for the shared counter. It can't create decks, pods or anything else.
No data is sold or shared for advertising, and there is no analytics or tracking software.
Your data is kept until you delete it or your account. Shared life counters are deleted when their game ends.
Download your data: sign in, then Menu > Download my data. You get a file with your profile, decks, friends, pods and the games you were part of.
Delete your account: sign in, then Menu > Delete account… (or open this link). You choose:
Either way, a pod you created passes to the member who has been in it longest (or is deleted if you were the only member), and games still in progress that you started are cancelled. Deletion is immediate and can't be undone. Things other people wrote themselves (their own answers about a game, for example) stay theirs.
You can correct your public name, username, playmat and decks at any time in the app.
DeckFlex is not directed at children under 13 and does not knowingly collect their data. If you believe a child has an account, please get in touch and it will be deleted.
Access is enforced by Firebase's security rules on the server, not just in the page: only you can change your own decks and profile, profiles can't be listed, and anonymous sign-ins can't write anything outside shared life counters. Traffic is encrypted (HTTPS).
If this policy changes, the date at the top changes with it. Questions, or requests about your data, by post:
DeckFlexYou can download or delete your data yourself at any time, without writing (see above).
