The short version: DD-420 stores everything on your device. We collect no personal data. Nothing is sent to any server. No accounts. No tracking. No ads. Your information stays yours — always.
DD-420 is an independent iOS wellness application designed to help military veterans track PTSD symptoms and cannabis use. The app was built by an Army veteran with TBI and PTSD, for veterans — from personal experience with PTSD and the tools that help manage it. It is published as a sole proprietorship.

We collect no personal data.
DD-420 does not require an account. We do not ask for your name, email address, phone number, location, or any identifying information.
All data you enter — check-ins, symptom logs, cannabis sessions, notes, settings — is stored exclusively on your device using Apple's SwiftData framework. It never leaves your device unless you explicitly choose to export or share it.
We do not collect, store, or transmit any of the following:
Every piece of information you log — symptoms, cannabis sessions, moods, triggers, notes — lives entirely on your iPhone. We have no servers that receive your data. There is no cloud sync. There is no backend database.
When you delete the app, all of your data is deleted with it.
All users can generate a full clinical PDF report to share with a VA provider or therapist. This report includes symptom data, cannabis logs, and usage patterns. It is generated entirely on your device and is not sent to any server. You control where it goes — you initiate the share, and iOS handles delivery via Messages, Mail, AirDrop, or any app you choose. We never see the contents of any report you generate.
DD-420 includes a free Caregiver Sharing feature available to all users. This allows you to share a simple wellness summary — such as recent mood trends or session counts — with a trusted caregiver, family member, or support person of your choosing.
This sharing is always voluntary and always initiated by you. We do not send caregiver data to any server. Sharing is handled through iOS's built-in share sheet (Messages, Mail, AirDrop, etc.), which means you control who receives it and how. We never have access to any shared content.
A future version of DD-420 may include optional integration with Apple Health (HealthKit) to read wellness data such as heart rate or sleep. If this feature is added, it will be strictly opt-in. Any HealthKit data accessed will remain on your device and will not be transmitted to any server. This policy will be updated before that feature is released.
DD-420 is 100% free. All features are available to every user at no cost. The app offers optional one-time tips ($2.99 / $4.99 / $9.99) as a way to support development — entirely voluntary, with no features locked behind them. Tips are consumable purchases processed by Apple through the App Store. We do not collect or store your payment information. We receive only a confirmation from Apple that a tip was completed — no financial details.
DD-420 may request permission to send local notifications (such as daily check-in reminders). These are generated and delivered entirely on your device by iOS. We do not use push notification services. No data leaves your device as part of the notification system.
DD-420 is designed for adults aged 18 and older and is rated 17+ on the App Store. We do not knowingly collect information from anyone under 18. If you believe a minor has used this app, contact us and we will assist in removing any locally stored data.
DD-420 does not integrate with any third-party analytics, advertising, or data-sharing services. There are no SDKs from Facebook, Google, Firebase, Mixpanel, or similar platforms in the app.
The only third-party platform involved is Apple — through the App Store and StoreKit — governed by Apple's own privacy policy.
Because your data never leaves your device, security is tied to your iPhone's security. We recommend using a passcode, Face ID, or Touch ID. If your device is lost or stolen, your data is protected by iOS device encryption.
Because we collect no personal data, there is nothing for us to access, correct, or delete on our end. All of your data is on your device, under your control. You can delete it at any time by deleting the app or clearing data in the app's settings.
If we update this policy, we will post the new version here and update the effective date. If the changes are material, we will notify you within the app. Continued use of DD-420 after a policy change constitutes acceptance of the updated policy.

A note from the developer: This app was built because veterans deserve tools that respect their privacy as much as their service. Your wellness data is yours. It always will be.
