Break-ups and shared access
Nothing revokes itself. The list to work through in one sitting, why the password matters more than the follower list, and how to replace what they were doing.
Access does not end when a relationship does. Somebody who followed your glucose data, held a spare key to your account, or was your emergency contact carries on holding all of it until you deliberately take it back.
- Nothing revokes itself. Every share is a separate switch you have to find.
- Do the list in one sitting: sensor followers, app logins, shared devices, emergency contacts, clinic records.
- Change the password too, since an account login gives access whatever the follower list says.
- Replace what they were doing. If they were your overnight safety net, that gap is now real.
- If the relationship was controlling, treat the data as part of it and get help rather than doing it alone.
Everything that carries on quietly
Start with the sensor and pump apps. A follow invitation accepted two years ago does not expire because you stopped speaking, so someone can still be watching without either of you thinking about it. Check the follower list in every app rather than assuming you remember who is on it.
Account access is the one people miss and the one that matters most. If they know your login, removing them as a follower changes nothing, because they can sign in and see everything or add themselves back. Change the password, and turn on two-factor authentication if it is available.
Then the rest of the list, which is longer than it feels: shared devices and old phones or watches still paired to your sensor, a tablet at their flat still signed in, cloud accounts and family sharing, your emergency contact details on your phone and with your clinic and your GP, medical identification you carry, and anything at work or university naming them. Clinic records are worth a specific call, because the person listed to be contacted about you is a real permission.
Doing it as one job, in one sitting, is far better than doing it piecemeal, because piecemeal means it is never quite finished and you never stop thinking about it.
Replacing what they were actually doing
If a partner was your overnight alert, revoking access leaves a genuine hole rather than just a tidier account. That is worth planning rather than discovering: another person to share with, and alarms you have actually tested that you wake to, since volume, do-not-disturb and charging the phone across the room all defeat an alarm quietly. Where you keep hypo treatment overnight, and whether anyone should be checking on you, are worth agreeing with your team rather than deciding alone, particularly if your hypo awareness is reduced. Living alone changes what you need here and is worth reading up on separately.
The same applies to the practical things they did without either of you noticing: knowing where your spare kit was, doing the pharmacy run, recognising your hypo signs before you did. None of that is dramatic on its own, and losing all of it in the same week as a break-up is a lot.
Be aware that the weeks afterwards often unsettle your diabetes as well as everything else, and not in any one direction: the whole routine it was built around changes at once, so glucose can be a good deal less predictable for a while, running higher on some days and dropping low on others. Which way it goes is individual and some people are entirely steady. If there is more drinking than usual, that carries its own well-established pattern, including a hypo that can arrive during the night or many hours later, and it is covered properly in parties, alcohol and staying safe. The point here is that a stretch of unpredictability is circumstances rather than a failure of self-management, and it is a legitimate reason to tell your team what is going on and ask for more contact.
Controlling behaviour, and getting help with it
Sometimes this is not admin. Health data can be used to monitor, to control, or to threaten, and diabetes data is unusually powerful for that because it says where you are, when you are asleep, whether you have been drinking, and how you are. If someone has used your numbers to check up on you, to accuse you, or to justify contacting you, that is coercive behaviour and it is not something you have to negotiate about.
If that is the situation, this page is not the right level of help, and the safe move is not to work through it alone. Domestic abuse services deal with technology-enabled control all the time, and they can help you plan what to change and in what order. In the UK the freephone National Domestic Abuse Helpline runs day and night, and if you are ever in immediate danger the number is 999. Your diabetes team can also help you get to the right support, and telling them is not an overreaction.
For everybody else, the ordinary version applies: work through the list, close the gap where they were helping, and be a bit gentler with yourself for a few weeks. Most of this is a twenty minute job that feels much bigger than it is.
What makes this bigger
Shared devices are the messiest part, since an old phone or a tablet left behind can still be paired to a sensor long after everything else is sorted. Being their emergency contact, or them being yours, is the one people forget entirely. And living alone afterwards changes the overnight question from tidying up to something worth planning properly.
What gets missed
Examples, not instructions or doses.
Removed from the app but the login unchanged. Signing in gives everything back, so the password is the real switch.
A device left at their flat, still paired and still receiving. Devices outlast relationships and nobody thinks of them.
The overnight alert gone with the person who had it. A genuine gap, and worth replacing rather than absorbing.
