Daily Doji

Legal

Last updated: 2026-05-29

1. Quick summary

Daily Doji is a mood tracker that lives on your phone. Your mood readings, notes and history are stored only on your device and we never see them. We send a small amount of anonymous data to our server and to Google services so the app works and so we can fix crashes.

2. Data stored locally on your device

The following never leaves your phone. Uninstalling the app deletes it all:

Your mood readings and the times you logged them
Any notes you write about a day
App preferences (theme, language, colors, reminders, etc.)

3. Data sent to third parties

We keep this to a minimum. These are the only cases:

3.1 Our server — promotional codes

What is sent: The promo code and a random installation ID (not linked to you).
Why: So the same device cannot redeem the same code twice.
When: Only when you enter a promotional code in Settings.

3.2 Google Play Billing — payments

What is sent: The data required to process your purchase (handled by Google, not by us).
When: When you buy PRO or restore a previous purchase.
Policy: policies.google.com/privacy

3.3 Firebase Analytics — anonymous usage

What is sent: Standard anonymous events such as first open, session start and app update, plus basic device info (model, OS version, country, language) and an anonymous Firebase installation ID. Your mood readings and notes are never sent.
Why: So we can understand which features people use and how often, to improve the app.
When: In the background, during normal use.
Operator: Google LLC — firebase.google.com/support/privacy

3.4 Firebase Crashlytics — crash reports

What is sent: If the app crashes, an automatic report is sent containing the error stack trace, device model, Android version, and an anonymous Firebase installation ID. Your mood readings and notes are never sent.
When: Only when a crash occurs.
Operator: Google LLC — firebase.google.com/support/privacy

4. What we do not collect

Your location
Your name, email, phone, age or any personal identifier
Your contacts, messages, camera or microphone
Your mood readings never leave the device. They are yours alone.

5. Permissions the app asks for

Notifications — for the quick-tap notification and daily reminders
Run in background — to keep the quick-tap notification visible
Start on boot — to restore the notification after restarting your phone, only if you had it enabled
Vibration — short haptic when you tap a mood from the notification
Internet — only for the limited uses above. The core mood tracking works fully offline

6. Your rights

Delete your data: Settings → "Delete all data" wipes everything stored on the device. Uninstalling does the rest. There is no account to delete.
Promo code records: the only thing we hold on our side is the link between your random installation ID and the codes you redeemed. Email us and we will remove it within 30 days.
Anonymous analytics: you can disable analytics for the app from your phone's system settings if you prefer.

7. Minimum age

Daily Doji is for users aged 13 and over. If you are using this app while monitoring a clinical condition, please involve a parent, guardian or qualified professional.

8. How long we keep data

Your phone: until you delete it in the app or uninstall
Google analytics: a few weeks, per Google's defaults
Crash reports: 90 days
Promo code records on our server: maximum of 90 days

9. Changes to this policy

If we change anything material, we will update the date at the top of this document. For changes that affect people in the EU/EEA, we will also notify you inside the app.

10. Contact

For any question about privacy or your data, email us at thejollysky@gmail.com. We try to reply within 30 days.

In short

Daily Doji is a personal mood tracker. By using it you agree to use it for personal use, accept that it is not a medical device, and understand that we are not responsible for decisions you make based on what the app shows.

1. Using the app

You can install and use Daily Doji on your personal device for your personal use, for free, with optional Pro features available for purchase. We grant you a non-exclusive, non-transferable license to use the app on devices you own or control.

2. What you should not do

Please don't:

Try to reverse engineer, decompile or extract the source code
Resell or redistribute the app or its content as your own
Use the app to harass yourself or others, or to harm anyone's wellbeing
Abuse promo codes (e.g. mass-redeem, share codes intended for others, or use bots)

3. Pro mode and purchases

Pro mode unlocks unlimited daily logging beyond the free tier. Pro is a one-time purchase processed through Google Play. Refunds, when applicable, are handled by Google according to their refund policy.

Promo codes can grant Pro time. They are not transferable and we may invalidate codes that are clearly being abused.

4. This is not a medical device

Daily Doji is not a medical, diagnostic or therapeutic device. The candles, moving averages and insights it shows are a way to visualize your own logging — they are not a clinical assessment. The app does not replace professional advice.

If you are concerned about your mental health, please contact a qualified professional or a local mental health support line.

5. Limitation of liability

To the extent permitted by law, Daily Doji and its creators are not liable for any indirect, incidental or consequential damages arising from your use of the app, including any decisions you make based on what the app shows. The app is provided "as is", without warranty of any kind.

6. Service availability

We try to keep the app and the small services it talks to (promo codes, crash reports) running, but we do not guarantee any specific uptime. Some features may stop working temporarily or permanently, with or without notice.

7. Ending the agreement

You can stop using Daily Doji at any time by uninstalling it. We can stop providing the app or the related services at any time. If you uninstall the app, all the data on your device is removed.

8. Changes to these terms

We may update these terms occasionally. The "Last updated" date at the top will reflect any change. If a change is material, we will tell you inside the app.
