问题
Do I have to put a copy of Privacy Policy inside the app itself, or should i only put the url to it inside google play without even mentioning it inside my app.
回答1:
Both as much as possible.
A public URL would most likely be required for that Privacy Policy field by Google Play Store if your app requests sensitive permissions.
If you don't add the URL and your app needs sensitive permissions, you'll receive a violation warning email from Google. Your app may be unlisted if you don't fix the violation.
Keep in mind that your business "must conspicuously link to a Privacy Policy".
That's a requirement from CalOPPA in the US, but most privacy regulations around the world have a similar requirement: PIPEDA in Canada, Privacy Act in Australia etc.
You have multiple options how to link to your Privacy Policy from within your app: About or Settings screen, Sign-up or Login screens, separate item in the menu etc.

In most cases the privacy policy is associated with the company that is publishing the app rather than the app. After all, that is the entity that people are trusting to implement the policy. So I think it is enough to have it on a company website and refer to this in Google Play. A key thing is that people should be able to search the web for the company name, or app and find the privacy policy. While not specifically about Android apps, the following link gives some guidance on this
Note that there are particular circumstances where user's need to be made aware of your approach to their data at the time they would be entering it. See Google's website
If your app collects and transmits personal or sensitive user data unrelated to functionality described prominently in the app’s listing on Google Play or in the app interface, then prior to the collection and transmission, it must prominently highlight how the user data will be used and have the user provide affirmative consent for such use.

You NEED your privacy policy on the Play Store page PLUS within the app
Since February 2017 Google enforces a strict privacy policy requirement on apps requesting sensitive permissions and user data policies.
Please check the following provided by Google to determine if either needs to have a policy or not:
- For apps that request access to sensitive permissions or data (as defined in the user data policies: You must link to a privacy policy on your app's store listing page and within your app. Make sure your privacy policy is available on an active URL, applies to your app, and specifically covers user privacy.
- For apps in the Designed for Families program: You must link to a privacy policy on your app's store listing page and within your app, regardless of your app's access to sensitive permissions or data. Make sure your privacy policy is available on an active URL, applies to your app, and specifically covers user privacy.
- For other apps: You're not required to post a privacy policy.
Once you've identified what your app needs, your privacy policy will need the following:
The privacy policy must, together with any in-app disclosures, comprehensively disclose how your app collects, uses and shares user data, including the types of parties with whom it's shared. Outline which sensitive permissions/user data you process and for what purpose:
Say you will access their microphone
Say what purpose that serves
And other user data you process (name, email, address, etc)
