Family Cards: Question Game — last updated 8 November 2026
All of this is stored only on your device, and none of it ever leaves it:
There is no account to create and no server holding a copy. Deleting the app deletes all of it.
Family Cards uses three services, plus TelemetryDeck in versions up to 1.4 (below). None of them receives anything you typed.
Each copy of Family Cards has its own ID: a long code of letters and numbers, like 6F9619FF-8B86-…. It is not your name, your Apple Account or an advertising ID, and it says nothing about who you are. It is kept inside the app, so deleting the app deletes it.
The app sends this ID to Sentry and PostHog (below), and versions up to 1.4 also send it to TelemetryDeck, so a crash can be matched with what happened in the game just before it. That is all it is for. We never use it to find out who you are, and it is never put in a feedback email.
If the app crashes or hits an error, Sentry receives a technical report: what went wrong and where in the code, the app version, your iOS version, your device model, a few device facts such as free memory and language, the last few steps before the problem (for example which screen was open, or that a button was tapped), and your app's random ID. It never includes what anyone typed. This is used only to fix bugs. Sentry is set not to keep your IP address or your location. Sentry stores this data in the European Union. Their privacy policy is at sentry.io/privacy.
PostHog receives events such as “a game was started”, “a round finished”, “the deck picker button was tapped”, “a card got a 👍 or 👎”, or “a deck was bought”, along with counts like how many players were in the game and how many rounds it ran. An event can say which deck and which card it was about, but never a name or an answer. It is used to see which parts of the game people actually use, which cards work, and which question decks to build next.
Every event carries your app's random ID and the time it happened, so events from one copy of the app can be put in order and matched with a crash report. Events also carry two counters that keep them in order (which time the app was opened, and the step within that time), and basic facts like the app version, iOS version, device model, screen size, language, time zone and whether the device is on Wi‑Fi. It never gets a name, an answer, or anything you typed.
PostHog is set not to keep your IP address and not to work out your location from it, and it makes no profile of you. PostHog stores this data in the European Union (Frankfurt, Germany) and keeps it for one year. Their privacy policy is at posthog.com/privacy.
Versions of Family Cards up to 1.4 send the same kinds of usage events to TelemetryDeck: version 1.4 sends them to both TelemetryDeck and PostHog, and earlier versions to TelemetryDeck only. From version 1.4.1 on, the App Store app sends them to PostHog only, and nothing to TelemetryDeck.
Each event also carries a scrambled device code that TelemetryDeck makes itself and scrambles again on its servers, so we cannot match it to your device. The one event that marks the app opening also carries your app's random ID, so it can be matched with a crash report. Events carry two counters that keep events in order (which time the app was opened, and the step within that time), and basic facts like the app version, iOS version and device model. TelemetryDeck does not store IP addresses, and it stores data in the European Union. Their privacy policy is at telemetrydeck.com/privacy.
Some decks cost money. Apple handles the payment: we never see your card, your Apple Account or your name. RevenueCat checks with Apple which decks were bought, so they unlock on your devices and Restore purchases works.
RevenueCat gives your copy of the app an anonymous customer ID (it starts with $RCAnonymousID:). Under that ID it keeps which decks were bought and when, and Apple's receipt for them. RevenueCat's code also sends basic facts like the app version, iOS version, device model, store country, language, and the ID iOS gives to all apps from one maker. There is no account and no login. RevenueCat stores this data in the United States. Their privacy policy is at revenuecat.com/privacy.
Settings has a Send feedback button. It opens your own mail app with a new email to yako@yako.dev. The app sends nothing by itself: you see the whole email first, you can change or delete any line, and nothing goes anywhere unless you tap Send.
Under your message, the email has a few lines that answer our first questions:
It never includes player names, scores, answers, or your app's random ID. We never use an email to look up your crash reports or usage counts.
We use your email only to reply and to help you, for example to check why a deck did not unlock. We do not add you to a mailing list and we do not share your email with anyone.
If you share the scores or a question, for example in Messages or to your Instagram Story, the picture goes only where you choose to send it.
Family Cards does not track you. There are no ads, no advertising identifiers, no third-party ad networks, and no data is shared with data brokers or used to build a profile of you. The app never shows the “Ask App Not to Track” prompt, because there is nothing to ask about.
Family Cards is made for families to play together, and children are expected to use it. The app never asks anyone, of any age, for personal information, and nothing typed in the game leaves the device. There is no chat, no messaging, no user accounts, no user-generated content that leaves the device, and no way for anyone outside the room to contact a player through the game. Purchases go through Apple, so parental controls like Ask to Buy work as usual.
Player names, scores and everything else in the game live only on your device. To remove them, delete the app.
Crash reports and usage counts are tied to your app's random ID, not to you, and we never look them up by your name or email. Deleting the app deletes the ID.
For your purchase record, email us your RevenueCat customer ID (Send feedback adds it for you). We can tell you what is stored under it, or delete it. Deleting it does not take away decks you bought: Restore purchases brings them back from Apple.
We keep your emails only as long as we need them to help you. Ask, and we will delete them.
If you would rather the crash and usage reports were not sent at all, email us and we will explain your options for the version you are running.
If this policy changes, the updated version will be posted on this page with a new date at the top. Material changes will also be noted in the app's release notes.
