A diary should feel like coming home.

Kindiary keeps every word encrypted on your own phone, and on the days you need it, hands your own sentences back to you.

Kindiary is a private Android diary and mood journal that helps you capture your day, understand your moods and look back on your life with a little more kindness.

Why Kindiary exists

Most diary apps want something from you.

Almost every free diary app on the store is paid for with your attention. The reviews tell the same story again and again.

Ads that keep coming

People pay to remove them, and the banners carry on appearing between one private page and the next.

Words that vanish

A new phone, a failed restore, no backup worth the name, and a year of writing is simply gone.

Guilt dressed up as a streak

You miss four days in the hardest week of your year, and the app greets you with a broken counter.

Kindiary is the deliberate opposite.

No ads before you pay and none after. Nothing leaves your phone unless you switch on backup yourself. Nothing is scored, and nothing shames you for coming back late. The weeks people stop writing are usually the hardest ones, and coming back is the good outcome.

Talk to your diary

Ask a question. Your own pages answer.

When did I last feel like this. What do I keep coming back to. Which day was my best one this spring. Ask in plain language and Kindiary answers from the entries you have already written. Pro

  • Runs entirely on your phone, with nothing sent anywhere
  • Every answer is drawn from your own words
  • It invents nothing and writes nothing for you

This is not a chatbot and not a language model. It reads what you wrote and takes you to the pages it found, so you can read the day for yourself.

Your own words, returned

The sentence you needed, on the day you needed it.

“I keep forgetting that this passes. Writing it down so that next time I remember.”

Written by you, one year ago today

Open Kindiary and a card offers you something you wrote. A line from a year ago. A thought from last night. A promise you made to yourself. Then it asks one short question about it. Never a summary, never a rewrite, only your sentence, chosen for the day you are actually having.

Build today’s story

Some days you have taps in you, not paragraphs.

One card on the home screen records a whole day without typing a word. Choose a mood, tap what was in your day, add the weather, and it saves straight onto today’s page.

  • Eight illustrated moods
  • Sixteen activity icons, from work and family to exercise and time outside
  • Weather picked by hand, or fetched for you
  • Free text tags for anything the icons do not cover

Track one thing Pro keeps one number beside the writing. Sleep, steps, water, energy, pain, cigarettes, or something you name yourself. Deliberately one thing, never a dashboard, and the days you leave blank stay blank rather than counting as zero.

However the day allows

Speak it, and your diary writes it down.

Some evenings you can write. Some evenings you can only talk. Hold the microphone and say what happened, and the words land on the page in your own phrasing.

  • Voice memos kept with the entry Pro
  • Rich text with titles, photos, sketches and stickers
  • Photos placed inline between paragraphs Pro
  • Twelve illustrated templates when a blank page is too much
  • Eight guided series across a stretch of evenings

  • More than twenty page backgrounds, or bring your own Pro
  • Your own accent colour Pro

Questions

The things people ask first.

Is it really free?

Yes. The free version is a complete diary with encryption, five themes, photos, moods, prompts, templates, search and export. It does not expire and it shows no ads. Pro is an upgrade, not an unlock of things you already needed.

Where is my diary kept?

On your phone, encrypted with AES 256 and a key derived from your passcode. There is no account and no copy of your writing on our side. If you switch on Google Drive backup, the copy that goes there is encrypted before it leaves the device, so it is unreadable to us and to anyone else.

What happens when I change phone?

Turn on encrypted backup before you move, then restore on the new phone with your 12 word recovery phrase. If you would rather not use backup at all, export your diary as a file and keep it wherever you keep things that matter.

Can I get my writing out again?

Always. Export the whole diary as PDF for reading, Markdown for editing anywhere, or JSON if you want the raw structure. No subscription is needed to take your own words with you.

Is there an iPhone version?

Not yet. Kindiary is an Android app on Google Play today, and we would rather say that plainly than promise a date we cannot keep.

Is talk to your diary an AI chatbot?

No. It runs on your phone, it is not a language model, and it writes nothing. It reads the entries you have already written and points you to the days that answer your question.

Will it nag me?

Only if you ask it to. You can set one daily reminder at a time you choose, and turn it off whenever you like. There are no streaks, no scores, and no messages about falling behind.
