Mar 24, 2024 at 7:57 comment added Nikita Kurtin @esentis This is a separate question. According to the policy of stackoverflow, it should be asked separately. Anyway, keep in mind that managing demos / trial versions can have business impact on your product, so I don't think there is one solution to match all cases.
Mar 5, 2024 at 11:03 comment added esentis Thank you for your detailed answer. However, what if you want to prevent trial abuse from users ? If the Firebase id is wiped when the user uninstalls the app, and a new id is generated on installation, you can't use this approach (from my understanding) to check if the ID was used in the past.

Feb 14, 2022 at 13:12 comment added Agent_L @famfamfam Because tracking devices is a privacy and security threat against users. There are no legitimate cases that call for it, so there is no reason to make it possible. Hw ids turned out to be mistakes and Google is slowly fixing them.
Feb 13, 2022 at 15:53 comment added Nikita Kurtin @ViktorBrešan In theory you're right. But this is a quotation from the Android official documentation: Avoid using hardware identifiers, such as SSAID (Android ID), IMEI, MAC address, etc... Specifically for my answer, I've stated what is the problem with this and other identifiers and then explained an alternative.
Feb 12, 2022 at 10:56 comment added Viktor Brešan How is SSAID hardware identifier? It changes on each factory reset and it is unique to each combination of app-signing key, user, and device.

Jul 21, 2020 at 10:39 comment added Nikita Kurtin @DavidSchneider the web-content is dynamic in its nature and the GDPR is just one of the examples, please note I've written " GDPR and similar regulations ", as there are many local and global regulations which affect your product / system / field. In any case the GDPR sections, that you are looking for are: Identification, Online identifiers and Data protection principles
Jul 21, 2020 at 9:55 comment added David Schneider Could you specify what section of the GDPR link you posted actually mentions the requirement for hashing IDs?
