All data stored by OTP Auth is stored using strong AES-256 encryption. This applies for all data. In particular, for both locally stored data as well as data stored in the iCloud Drive (when iCloud Sync is enabled). The password for those files never leaves your device such that noone but you can read your data.
OTP Auth does not collect information about you or send them anywhere. You won't be asked to allow access to your contacts or your location. And most important: OTP Auth does not connect to the internet and will not send your accounts to someone else! (Unless you enable iCloud sync where an AES-256 encrypted copy of your accounts is stored in your iCloud Drive. The password for that copy will never leave your phone.)

Perfect way to secure your online logins
After having tried about a half-dozen similar apps, stumbled upon this simple authenticator that works great. I like the ability of adding an entry one one of my iOS devices, and have it sync to all my other iOS devices. Another nice feature is that I can sort my entries, and add categories (folders) to put them in, so I can have a folder for home (personal) sites, another for work ones, and yet another one for rarely-used sites, etc. It is capable also of allowing me to change the icon of each entry with an icon of my choosing, and I can rename the name of each entry, as well as the email address associated with each entry. As for support, the author was quick to reply to my requests for help on a couple of occasions (when I had issues due to my own stupidity, I might add). The icing-on-the-cake of this app, is that I can also see all of my entries on my Apple Watch, with the press of an icon on my watch face. Well-worth the cost of the Pro version of this app!
What Convinced Me
App has -great- features and support, but what ultimately convinced me to switch? Steve Gibson's recommendation on SecurityNow! Steve is security expert and was longtime Google Authenticator user and advocate before switching to OTP Auth in 2018 (episode #679). The clincher was episode #719, in response to a listener request: "Could you maybe recommend the two-factor authentication app that has some organization behind it and has the Steve Gibson seal of approval? I can't be the only listener with this problem." Steve continues: "Well, so it just so happens ...". Interested? Download episode #719 and search for 'Pastuszak' (the listener's last name). Also,'Show Notes' download for this episode has nice summary that includes iOS App Store developer's app info and links. In episode #750 Steve says OTP Auth is his 'favorite app on the iPhone'. Steve leaves no stone unturned, including apps he personally uses. He vets them well. If it's good enough for Steve, it's good enough for me.
what a great app!
this is such a perfect app and it does its job so well. i’ve been sifting through authentication apps the past day or so and have tried authy, bitwardens premium feature, duo and so on and this is by far the best one of the bunch. the way the app blends in perfectly with iOS is just reason alone to use it! the UI is so fluid and enjoyable to use and so well thought out. seriously, this is great. would you ever consider making extensions of this app for browsers? i’d love for this to sync with safari or even firefox too. (maybe that defeats the purpose of having 2FA? maybe.) but anywho, if you’re stuck pondering on what app to get for any authentication purposes, get this one, the rest will only be downgrades imo.
