Answer a few questions about your app or website and get a privacy policy that matches - with the services you use, data deletion steps and your permissions. Download it as a ready-to-host HTML page, plain text, Markdown or PDF.
Yes, if your app collects any user data - and almost every app does (even analytics, ads or crash reports count). Google Play asks for a public privacy policy URL in the store listing and expects it to match what you declare in the Data safety form.
Download the HTML page and upload it to your website (for example yoursite.com/privacy). Then paste that address into the Google Play Console under App content, and also link to it inside the app. Do not use a PDF link or a page that needs a login.
No. It is a template built from your answers. Check that every statement is true for your app, keep it up to date when you add new services, and get legal advice if you handle sensitive or children's data.
The ticks you make here (data collected, third-party SDKs, deletion method) are the same facts the Data safety form asks about, so it is a good checklist to keep both consistent.
