Here's a scenario the system doesn't plan for but happens constantly: you change prescribers. You move house and register with a new GP. Your usual prescriber is on leave and you see a locum.
You transfer from a private or telehealth clinic to NHS care, or the other way. And at every one of those handoffs, the new person in front of you starts with very little of your history, because records don't follow you as cleanly as everyone assumes — especially across the private/NHS line or when you move. So the appointment opens with 'tell me about the last several months,' and you're reconstructing from memory something you were never specifically trying to memorise.
The fix isn't to fight the system — it's to keep your own continuous record so the handoff has something to stand on. A simple log of your dose dates and a brief weekly note means that when you sit down with someone new, you can show them a timeline of the past several months in thirty seconds instead of guessing. And this is where keeping the data on your own device genuinely matters, not as a slogan but practically: the record is portable because it's yours.

You're not asking a clinic you've left to release anything. You're not locked out of your own history because you changed providers. You open your phone and there it is.
None of this is medical decision-making — the prescriber does that. It's just organised record-keeping that happens to be the one piece of continuity that travels with you. If there's any chance you'll change prescribers in the next year — and most people will, eventually — the record you keep yourself is the one that'll still be there when you do.
