Largo privacy policy
The short version. No account, no ads, no tracking, no analytics. Your progress and settings stay on your device. The app contacts one service, RevenueCat, to check whether the Puzzle Club subscription is active.
Who we are
Published by Prax, an individual developer. Contact: praxappssupport@gmail.com.
What we collect
We do not run a server for the app. Puzzles are bundled in the app or generated on your phone. When the app starts it contacts RevenueCat, which handles subscriptions for us:
| What | Why | Linked to you? |
|---|---|---|
| An anonymous app user id that RevenueCat generates (no name, no email, no account) | To recognise this install and check whether Puzzle Club is active. | Only to that anonymous id. |
| Purchase and subscription status (plan, dates, trial, renewal, store receipt) | To unlock Puzzle Club, restore purchases and show the right plan. | Only to that anonymous id. |
| Technical data sent with any network request, such as IP address, device model, OS and app version | To deliver the service and prevent fraud. | Handled by RevenueCat as our service provider. |
The app has no advertising SDK, no analytics SDK and no crash-reporting service, does not use the advertising ID and has no account or sign-in.
What stays on your device
- Your puzzle progress, statistics, daily "run" count, settings (text size, contrast, theme, sound, timer) and your entitlement status are stored on your phone.
- The optional daily reminder is a local notification scheduled on your phone; it is off unless you turn it on.
- Printing creates a PDF on your device and hands it to your phone's print or share system.
- Links you tap (privacy policy, terms, support email) open your browser or mail app.
Who we share data with
We do not sell or share personal information for advertising.
| Company | Role | What it receives |
|---|---|---|
| RevenueCat | Subscription management for us. | The anonymous id, purchase status and technical data described above. |
| Google Play (Android) / Apple App Store (iOS) | Process your payment and subscription. | Handled under their own privacy policies. We never see your payment details. |
Retention and deletion
- On your device: kept until you clear the app's data or uninstall it.
- RevenueCat: keeps purchase and subscription records linked to the anonymous id for as long as needed for billing, restore and legal reasons. To ask for these records to be deleted, email us and we will ask RevenueCat to delete your anonymous id.
- To ask us to delete the anonymous purchase id, email us with your app version and store (we may need your store order id to find it). There is no puzzle account to delete.
Children
The app is for a general audience, built for readability. It is not directed to children under 13 and we do not knowingly collect their data. It has no ads and no account, and collects nothing beyond the subscription check above.
US state privacy rights
If you live in California, Colorado, Connecticut, Virginia, Texas, Utah or another US state with a consumer privacy law, you may have these rights, which we offer to everyone:
- Know and access: ask what personal information we hold about you and get a copy.
- Delete: delete your data by clearing the app's data or uninstalling; to ask us to delete the anonymous purchase id, email us.
- Correct: ask us to fix information that is wrong.
- Opt out of sale, sharing and targeted advertising: Largo does not sell your personal information, does not share it for cross-context behavioral advertising, and shows no ads, so there is nothing to opt out of.
- No retaliation: we will not treat you differently for using these rights.
To use a right, email praxappssupport@gmail.com. We may need to confirm it is really you before we act. You can use an authorized agent; we may ask for proof of their authority. If we turn down a request you can reply to ask us to reconsider (appeal) and, depending on your state, contact your state attorney general. We aim to answer within 45 days.
Changes
If we change this policy we will update the date above and, for material changes, tell you in the app.
