Apparently Apple has fixed the clipboard counter in iOS 27 beta 3 thanks to Loupe. ✌️ Now the counter resets after a restart. Hey Apple, a little shoutout to the Loupe project would have been nice! Loupe is free and open source. You can download Loupe here: apps.apple.com/us/app/loupe...

Privacy tip: If you hide an app on iOS, other apps cannot detect it and won't know if you have it installed. This is confirmed by Loupe and you can test it✌️

Oh, 1Password stores user profile pictures on their servers without authentication. Anyone who has the long URL, which also contains the account identifier, can access the picture. It's not a big deal, but a password manager should definitely be more careful. #privacy

Why do all browsers in iOS 26 communicate with this Google service? Has Apple changed how safe websites are downloaded? Psylo tunnels all connections via our proxy servers to prevent IP leaks. How are these calls made? Does Google see the real IP? #Privacy #Apple #iOS26

What a productive day! I accidentally time-traveled to the year 2076, created an Excel sheet, and returned. But that's not the puzzling part. I still can't believe that an Excel file can be so backward compatible.

X has introduced its end-to-end encrypted chat feature. This service utilizes the Juicebox protocol, which enables users to secure their encryption keys with a simple, memorable 4-digit PIN while defending against brute force attacks. X’s implementation is wrong because they own all the realms 🧵 1/2

Just signed in from another browser session and was able to recover the messages by entering the PIN. The encryption keys are clearly stored remotely and this PIN is used to decrypt their vault. You need 10,000 iterations to brute-force it.

iOS 18.6 patches 12 WebKit vulnerabilities. Since Apple requires all browsers on iOS and iPadOS to use WebKit, these CVEs affect Safari and all browsers. Individual browser patches aren't possible since Apple updates WebKit alongside the OS. (iOS 18.5 was released 79 days ago)

Psylo deliberately doesn’t offer a share feature due to a privacy issue in iOS’s share feature: it generates a link preview of the website you’re sharing using your IP address, which bypasses Psylo’s tracking protection. You can tap and hold the address bar to copy the address.

That doesn't seem to be purely intentional by TikTok. A few days after releasing Psylo, an ad for Perplexity started to show up when you search for Psylo, it is highly unlikely that Perplexity had added "Psylo" as a keyword to their ad campaign:

If you accept the cookies, you will be tracked with that silo only. We made it very hard for the same website to track Psylo users across different silos. You can check out the "ephemeral" option, it clears storage when exiting the silo:
