One of the easiest things to miss on a phone is not the answer itself, but where your record is actually being stored.
If records only live locally, a new phone or cleared cache can cut them off. If they live with an account, the sync logic still needs to be real.
Separate local storage from account storage
Local storage is quick for trial use but fragile across device changes.
Account storage is better for long-term continuity, but only if the service really connects login, orders, and history.
Two common failure points
Example 1: you ask a lot on one phone, then lose the trail after clearing cache because you never left local-only mode.
Example 2: you pay after logging in, but device states still feel inconsistent because the sync path is unclear.
What a calmer save flow looks like
A better system lets you try lightly first, then clearly explains what follows the account later.
If that layer is unclear, the product is not mature yet in continuity terms.
What to check before changing phones
- Check whether you are local-only or logged in.
- Check whether history, orders, and membership really follow the account.
- Only then change devices or clear storage.
