Mindlog is a quiet place to write down what you are thinking and how you feel. No account. No cloud. No tracking. Your entries stay on your device and nowhere else โ€” there is no server for them to go to. WHAT'S INSIDE โ€ข Quick entry โ€” opens the moment you launch the app, so a thought does not disappear while you look for a button โ€ข A map of emotions โ€” find the word that actually fits instead of settling for "fine" โ€ข Your own history โ€” browse and filter past entries, and notice what keeps coming back โ€ข Short reads and exercises โ€” a small built-in library on working with your thinking more clearly โ€ข App lock โ€” optional Face ID or Touch ID, and the screen blurs itself in the app switcher โ€ข Exports you control โ€” PDF, JSON or a spreadsheet, whenever you want them โ€ข Encrypted backups โ€” AES-256-GCM, with a passphrase only you know โ€ข Fully offline โ€” no connection required, ever PRIVACY IS THE ARCHITECTURE Mindlog contains no analytics library, no advertising SDK and no backend. That is not a promise we are asking you to trust โ€” it is the reason there is no mechanism for your writing to leave your device in the first place. Available in English and Russian.

HOW TO USE SPARKNOTE 1) Write a line about your day, or say it out loud 2) In seconds, Eureka replies and names how you felt 3) At night, tap Digest to turn the day's notes into one diary entry SparkNote is the AI journal that writes back. Jot down whatever is on your mind, from a skipped lecture to a long call with Mum. Eureka reads each note, names the feeling behind it and answers like someone who knows you. It remembers what matters to you, so the more you write, the more personal the replies get. WHAT YOU CAN DO โ€ข Choose who writes back: insight, comfort, a push to decide, or a voice you write yourself, like a study coach or a horoscope. โ€ข See your mood without tapping a thing. Every note gets a feeling, shown as weather, and Stats shows your weeks and months. โ€ข Let Smart Digest learn from your day, so Eureka remembers more about you next time. โ€ข Connect Apple Health to see sleep, steps and heart rate next to how you felt. Heart rate and HRV need an Apple Watch. โ€ข Add photos, or talk instead of typing. โ€ข Lock your journal with Face ID or Touch ID. Notes stay on your iPhone, and a note only goes to the AI when you ask for a reply. FREE AND PREMIUM Writing and keeping your journal is free. Your first 10 AI replies are free too, with every feature open. After that, SparkNote Premium gives you 50 replies and 10 digests a day, photos, dictation, weather and mood insights. Monthly or yearly, with a free trial. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://lufeizhou.github.io/SparkNotePrivacy/
