Older straight cis male here, so pardon me if I screw something up. Genuinely trying to help, but I admit I still struggle with old programming.

Also, I’m not some security guru so confirm my technical suggestions for yourself.

That said, my thoughts:

• Try not being so specific as to when you’re leaving. “Soon” is useful enough without reducing the possible time frame to well under 10% of the possible dates for anyone who might somehow be cyberstalking you. I’m no opsec expert, but it seems to me that you should try being as vague as possible, whenever possible.

• if you’re not planning on completely wiping your phone, consider setting up an app like the FOSS app Oblivion, which can wipe your phone under certain conditions similar to the person who made the news in the past week.

• Alternatively, I’ve read you can set up an alternative profile as the main one on your phone - using it for a bit every day for superficial shit to build a genuine-looking usage history. I’ve never done this, so I can’t help much here. If you do this, and they question why there’s so little history (if they even get to the point where they can read it), tell them your old phone broke & you bought this used to replace it.

• Also turn your phone off completely no later than upon arrival at the airport (the sooner, the better). I’ve recently read that an encrypted phone is thoroughly & completely secured when first turned on until you unlock it for the first time, so it will be unreadable to any three-letter agency no matter what tricks they have unless they have the unlock code (which you should probably also change the night before to give the phone time to process/perpetuate the change).

• I presume you’re gonna go appearing as the sex your body currently most presents as to minimize potential unwanted attention.

Sorry I can’t be more help, but hopefully I’ve mentioned something you didn’t know or think of. Much luck!
