The short version: DBT Daily does not collect, transmit, or share your diary entries or any personal information. Everything you log — mood, anxiety, urges, stress, skills, notes — stays on your device only.
1. Who We Are
DBT Daily: Diary Card & Skills is developed and published by DahVio Studios, a solo developer studio based in Long Beach, California, operated by Ray (ray@dahvio.com).
2. The Data You Enter — and Where It Lives
When you use DBT Daily, you may log the following information:
- Mood, anxiety, urge, and stress levels (numeric slider values)
- DBT skills you used during the day
- A free-text personal note
- Areas of personal challenge (selected during onboarding)
The app also saves your preferences:
- Daily reminder time (if you set one)
- Onboarding completion status
- Whether you've seen the skill hint tooltip
This data is stored exclusively on your device using iOS's standard local storage system (UserDefaults/shared_preferences). It is never uploaded to a server, never synced to the cloud, and never transmitted anywhere — not to DahVio Studios, not to Apple (beyond standard App Store operations), not to anyone.
3. No Account Required. No Backend.
DBT Daily has no user accounts, no sign-in, no registration, and no server infrastructure of any kind. There is no backend that receives, stores, or processes your data. We have no way to access what you log because it never reaches us.
4. No Analytics or Crash Reporting
DBT Daily does not include any of the following:
- Analytics frameworks (e.g. Firebase Analytics, Mixpanel, Amplitude)
- Crash reporting tools (e.g. Crashlytics, Sentry, Bugsnag)
- Advertising or tracking SDKs
- A/B testing or feature flag services
- Any third-party SDK that transmits data to an external service
We do not know how often the app is opened, what features are used, or whether it has crashed. We have no behavioral telemetry of any kind.
5. One Limited Network Request — Google Fonts
DBT Daily uses the DM Sans typeface via the Google Fonts service. On first launch (or when the font is not yet cached on your device), the app may make a request to Google's font servers (fonts.googleapis.com / fonts.gstatic.com) to download the font files.
This request involves Google receiving your device's IP address and standard HTTP request headers. Once downloaded, the font is cached locally and no further requests are made. This is the only outbound network activity the app performs.
This request contains no diary data, no personal health information, and nothing specific to you or your use of the app. For more on Google's data practices, see Google's Privacy Policy.
6. Local Notifications
If you enable the optional daily reminder, the app schedules a local notification on your device at your chosen time. This notification is generated and delivered entirely on-device — no server is involved, and no data leaves your phone to trigger it.
You can disable reminders at any time from within the app or from your device's notification settings.
7. Deleting Your Data
To permanently delete all data stored by DBT Daily — including all diary entries, notes, and preferences — simply delete the app from your device. No additional steps are required, and nothing is retained on any server because nothing was ever sent to one.
8. Children's Privacy
DBT Daily is rated 4+ on the App Store and is intended for general audiences. The app does not knowingly collect any personal information from anyone — including children under 13 — as it does not collect personal information from any user.
9. App Store Data Practices
While DahVio Studios collects no data through DBT Daily, Apple may collect certain app usage data as part of standard App Store and iOS operations (such as crash reporting if you have opted in to share diagnostics with Apple). Please refer to Apple's Privacy Policy for details on their practices.
10. Not a Medical Device
DBT Daily is a personal journaling and skill-tracking tool. It is not a medical device, not a clinical diagnostic tool, and is not intended to replace professional mental health care, therapy, or crisis services. If you are in crisis, please contact a qualified mental health professional or a crisis line in your area.
11. Changes to This Policy
If our data practices ever change, this policy will be updated with a new effective date and the change will be noted in the app's release notes. Given the no-server, no-analytics design of this app, material changes are unlikely — but we'll be transparent if they occur.
