Not good enough. It's on you to notify the end user of privacy policy changes. Not simply rely on them to check the policy from time to time.
And for anyone wondering who Coupon Clash is:
I will fix it, backend is firebase firestore and google login auth, its just a reminder app, i made for myself, as there is already a app buts its full of ads and charges 34$ per year.
I checked the other app and found that they don't have cloud save and multiple user lost there list when they switch devices, plus if you want you data and account deleted there is a google form, mention in the playstore, just email or fill the form and i will delete all the data.
