StarwrightAt a glance
- No sign-in, no name, no email address. The app never asks who you are.
- Your progress, streaks and settings stay on your phone. Only your streak and chart count travel with usage data.
- While “Share usage data” is on, the app sends game events tied to a random device ID, not to you. Switch it off in Settings, under Privacy.
- Crash reports, with no IP address and no user identifier, help us fix bugs.
- One kind of ad: an optional video you can choose to watch for a hint. It is never personalised.
- We do not sell your data, and nothing here is used to target ads at you.

Who is responsible
Starwright is published by Papalote Studio, an independent studio. Papalote Studio decides how the data described here is used. For anything about this policy or your data, write to support@playstarwright.com.
On your phone
The app keeps its state on your phone: your streaks and solve history, the chart you are working on, whether you have seen the introduction, your chosen edition, your Patron unlock, and your privacy settings. None of it is sent to us, with one exception: while “Share usage data” is on, two summary numbers travel with the usage events described below, your current streak and how many charts you have completed. Uninstalling the app, or clearing its storage, removes everything on your phone.
The optional evening reminder is scheduled on your phone too. Nothing is sent to a server, and you can turn it off in the app’s Settings or in your phone’s settings.
Usage data
While the “Share usage data” switch is on, the app sends game events to PostHog, an analytics service that stores them for us in the United States. The switch is on by default. Turn it off in Settings, under Privacy, and collection stops immediately. The game works the same either way.
Each event carries a random ID created on your phone. It identifies the installation, not you: we never link it to a name, an email address or anything else. In law it still counts as pseudonymous personal data, so we treat it that way.
What an event contains:
- What happened: a chart started, finished or left; a hint or check used; a share; your streak changing; a screen opened; the Patron screen opened or a purchase completed.
- Details of the chart: its number, date and difficulty, how long the solve took, and how many hints and checks you used.
- Your progress: your current streak and how many charts you have completed.
- Onboarding: the step you reached and whether you skipped it.
- Ads and purchases: the type of ad shown and whether a hint ad finished; when you buy Patron, the product and its price.
- Technical details PostHog’s library adds: the screen size, that it is a mobile device, the library’s version and, where the phone reports them, the app’s name, version and build. It does not add your phone’s model, operating system, language or time zone.
What is never sent: your IP address is discarded on arrival, there is no session recording, and the stars and marks on your board stay on the phone.
Why we do this. We have a legitimate interest in knowing which charts are too hard, where new players get stuck and whether a release broke something. A small studio cannot test every device itself. Because the data is pseudonymous, limited to the game and easy to switch off, we believe this does not override your interests. You can object at any time with the switch.
Every event name
app_open, onboarding_step, onboarding_completed, daily_started, daily_completed,
daily_abandoned, hint_used, error_check_used, share_tapped, streak_updated,
atlas_opened, ad_shown, patron_screen_viewed, purchase_completed, restore_tapped,
screen_view, and the events PostHog’s library records on its own: Application Installed,
Application Updated, Application Opened, Application Became Active and
Application Backgrounded.
Crash reports
If the app crashes, a report goes to Sentry, an error service that stores it for us in the United States. A report contains the error, a short trail of the app events leading up to it, and the app and device details Sentry attaches, such as the app version and the device model. It carries no IP address and no user identifier. Sentry’s session tracking is off, and puzzle solutions are removed before anything is sent.
We rely on our legitimate interest in keeping the app working. Crash reports are not affected by the usage-data switch, because without them we cannot fix a crash you are having. If you object to them, write to us.
Ads
Starwright shows one kind of ad, through Google AdMob: a video you can choose to watch in exchange for a hint. Watching is never required to play. If you choose not to watch, or close the ad early, you go without that hint and carry on. If no ad can be shown, the hint is granted anyway. Patron players never see it.
Ad requests are non-personalised: Google does not use your interests or history to choose the ad. To serve it, measure it and prevent fraud, Google may still use device identifiers such as your phone’s advertising ID, and your IP address. Google is responsible for that data under its own privacy policy, and explains how it uses information from apps that show its ads.
In the EU, the UK and Switzerland, Google’s consent form appears before any ad, with Consent, Do not consent and Manage options. You can change your answer at any time in Settings, under Privacy, with “Ad privacy choices”.
Purchases
The Patron unlock is sold and processed by Google Play under Google’s privacy policy. We never see your payment details or your Google account. The app only learns that the purchase succeeded, so it can unlock Patron and restore it later.
Emails to us
If you write to us, we receive your email address and whatever you include, and use them only to answer you. We delete the conversation 12 months after the last message, or sooner if you ask.
Where your data goes
PostHog, Sentry and Google are based in the United States, so usage data, crash reports and ad data are processed there. Where EU or UK law requires safeguards for these transfers, we rely on the ones each provider offers in its data processing terms, such as the EU-US Data Privacy Framework or the European Commission’s standard contractual clauses. Write to us for the details of a particular provider.
PostHog and Sentry process data only to provide their service to us. Google uses ad data under its own privacy policy, as described under Ads. We do not sell personal information, share it for targeted advertising, or give it to anyone for their own marketing.
Keeping it safe
Everything the app sends travels over an encrypted connection, and only the people who make Starwright can see the usage data and crash reports.
Your rights
Depending on where you live, you have the right to:
- access the data we hold about you, and get a copy in a portable format;
- correct it, or have it deleted;
- object to our use of it, or ask us to restrict it;
- withdraw consent where we rely on it, without affecting what happened before;
- not be discriminated against for using these rights.
The quickest ways need no email: switch off “Share usage data” to stop analytics, change your ad choice in Settings, or uninstall the app to remove everything on your phone. For anything else, write to support@playstarwright.com. Because we hold no name or email address, we may not be able to match a request to stored events; if so, we will tell you. We answer within one month.
If you are not happy with our answer, you can complain to your data protection authority. In the UK that is the Information Commissioner’s Office; in the EU, your country’s authority.
Starwright makes no decisions about you by automated means, and you never have to provide any of this data to play.
Children
Starwright is made for a general audience and is not directed at children under 13. We do not knowingly collect personal information from them. If you believe a child has sent us information, for example by email, write to us and we will delete it.

Changes to this policy
When this policy changes, we update the date at the top and add a line below saying what changed.
- 3 October 2026: rewritten to state the legal basis, retention period and recipient for each kind of data, add your rights and international transfers, and describe the device ID as pseudonymous rather than anonymous. Removed mentions of Practice charts and of ads between charts, which the app no longer has.
- 29 September 2026: first version.
