Thanks for all those responses so far i really appreciate it.
My OP was primarily seeking advice as I want to be able to sort my privacy settings independently so that I have control over my own devices. I don't want to go running to DH for help every time I need it. Also, my concern is if DH can get hold of photos from my phone, can my teenage kids do the same? In addition to the pictures I already mentioned I've also got screen shots of a private nature: important paperwork for my DM and DB I'm helping out with and other sensitive things that I keep for ease of reference as I need to quickly open files and discuss them if, for instance, my DM's health practitioner calls me, etc. I won't bore you by listing everything. My DH is not known for his discretion (even on his own private matters sometimes - he simply cannot help himself!!@), so although he is aware of what is going on with my DM & DB he doesn't know all the ins and outs. Most things on my phone I'm fine about being seen by my family, but there are certainly some things which are for my eyes only due to their sensitivity. I certainly am not up to anything sordid, I've neither the time not the inclination!
In answer to some of your questions:
• @Merlott Can I prevent my phone being paired on Bluetooth without my knowledge
• @ssash What is NFC? Some kind of sharing method? Again, can I set up my privacy to avoid this?
• @rattlemehearties @GloriousGoosebumps Yes, my phone has a passcode. I do change it regularly so I doubt DH knows my current code. He did know some of my old ones, but I don't keep updating him. He has got my passcodes to my laptop and he's welcome to look at whatever he wants on there.
• @CraneBoysMysteries - love your username! No, I don't have an iPhone I'm on android
• @Sandysandwich Yes, I am on Google photos but when I checked it didn't have the photo in question. I was surprised by what WAS on it though. However, I must have disabled the automatic syncing as my photos have not been shared on there for ages
• @frenchnoodle Our googledrive accesses are separate. I'm not even sure he's got googledrive. He doesn't trust Google fullstop.
• @AltitudeCheck he is 100% aware that I have alopecia and he knows I feel very sensitive about it. He also knew I had photos which I've taken to keep a record of its progress. He knows I don't want him to see the photos and I've explained why. He doesn't agree that he shouldn't see it, but reluctantly accepts that's how i want it.
• @maddy68 I didn't share the picture with anyone on social media or with anyone anywhere else (email, WhatsApp, etc).
Some of you have guessed that I am concerned he will react badly if I ask. This is highly probable, yes. Either that or he'll be evasive. This is why I can't "just ask him" - if that was an option I would of course have done this. I wish i could. Anyway, I deal with his moods in my own way and I don't want relationship advice if that's OK please? What I would LOVE to get from this thread is to become more empowered with my own device.
Thank you those who have commented and helped so far, if anyone else has any insights I would be so grateful hearing from you. And particular thanks to those who recognise I'm entitled to some privacy on my own phone.
