A DBT diary card on your phone
DiaryLog is a diary card for people in Dialectical Behavior Therapy. Note your urges, emotions and the skills you used in about a minute a day, look back over the week, and bring it to your next session. It supports therapy and doesn't replace it.
Get it on Google PlayAndroid. Free: the daily card, week view, skills library, Help now, reminder, app lock and backup. DiaryLog Pro, one in-app purchase paid once: the card as a PDF, CSV export, trends, and your own items.
What it does
Today's card
Urges from 0 to 5 with "acted on it", emotions from 0 to 5, the skills you used, the 0 to 7 skills-use scale, a note, and medication if you choose to track it. It saves as you go. You can fill in a past day too.The week
The card as a grid, one column per day, shaded by intensity, with skills counted. Tap a day to change it.Skills library
Short reminders, in our own words, of 28 skills across four areas. They are for skills you learn and practise with your therapist or skills group.Help now
On the Today screen and in Settings: emergency guidance, a crisis line where we know your region's number, and a helpline finder for other countries. Always free.Reminder, lock, backup
A daily reminder at a time you choose. An app lock using your fingerprint or device passcode. A backup file of your whole diary, which you can restore on a new phone.DiaryLog Pro
One optional purchase, no subscription. Share the card as a PDF of 1, 2 or 4 weeks, export CSV, see trends over 30 or 90 days, and add your own items.Where it helps
- If you are in DBT and would rather keep your card on your phone than on paper. Check with your therapist that a phone suits them. How people use a card with their therapist.
- If privacy matters to you. Your diary stays on your phone. The app has no account, no ads and no analytics, and it doesn't connect to the internet.
- If you would like to know more first. Read what a diary card is. A card on its own isn't therapy. A doctor or mental health professional can talk through whether DBT might suit you.

Frequently asked
Is DiaryLog a treatment? No. It is a diary card, the tracking sheet used in Dialectical Behavior Therapy, to support the work you do with your therapist or skills group. It doesn't replace professional care, it isn't a crisis service, and it isn't a medical device. It doesn't diagnose or treat any condition.
Who can see my diary? Only you, unless you choose to share it. Your entries stay on your phone. DiaryLog has no account and never sends your entries anywhere. You can lock it with your fingerprint or device passcode (Settings, App lock).
Can I fill in a day I missed? Yes. Use the arrows or tap the date on the Today screen, or tap a day on the Week screen.
What does the free version include? The full daily card (urges, emotions, skills, the skills-use scale, medication, notes), the week view, the skills library, Help now, the daily reminder, app lock and backup. You can also hide items that don't apply to you. DiaryLog Pro, a single purchase, adds sharing the card as a PDF (1, 2 or 4 weeks) and CSV, trends over 30 or 90 days, and your own targets, emotions and skills.
Is there a subscription? No. DiaryLog Pro is a single purchase. Restore it on a new phone from Settings.
How do I move my diary to a new phone? Settings, Back up saves a file with your whole diary. Send it to yourself, then use Settings, Restore on the new phone. The file holds everything you wrote, so take care where you send it.
Where do the skill descriptions come from? They are short reminders in our own words. Learn and practise the skills with your therapist or skills group.
Privacy policy
Effective 6 November 2026. DiaryLog is published by Eastframe Technology LLC.
What we collect: nothing. DiaryLog has no account system, no analytics, no advertising, and no crash reporting service. It sends no data to us or anyone else, and it works without an internet connection.
Your diary (ratings, skills, medication answers and notes) is stored only on your device, until you delete it or uninstall the app. Backups and exports are files you create and send where you choose, through the share sheet.
App lock uses your device's Face ID, Touch ID, fingerprint or passcode. The check happens in the operating system; DiaryLog never sees your biometric data or passcode.
Reminders are scheduled on your device.
Purchases are handled by the App Store or Google Play. We do not see your payment details. On Android, the app includes Google Play's billing library, which has the internet permission and connects to Google Play to handle purchases. Google's privacy policy applies to that connection.
Third parties. The app contains no third-party advertising or analytics code. The only external pages it opens are this one and findahelpline.com, and only when you tap them.
Children. DiaryLog is not directed at children under 13 and collects no personal information from anyone.
Changes. A new version of this policy will be published at this address with a new effective date.
