Privacy by design
Your data stays yours.
Core health and training records stay on your device. Diorama does not sell that data, use it for advertising, or track you across other companies' apps and websites.
Start without a Diorama login.
Diorama keeps your training, sleep, recovery, health, and journal records in protected storage on your device. You can use the app locally without a Diorama login.
Your health data is not ad inventory.
Diorama does not sell your health or training data, share it with advertisers, or use it to track you across other companies' apps and websites.
Your records stay on your device.
Core health, training, recovery, and journal records remain in Diorama's protected app storage. Cloud services receive only the limited information described in the privacy policy when you use features such as Ray, analytics, feedback, or subscriptions.
Share with who you want.
Export a report or share information with a coach, clinician, or service you choose. You choose the recipient, the moment, and what leaves the app.
Usage data, not health values.
Product analytics can show that a screen opened or a feature ran. They do not include health values, journal text, pain details, or AI conversations. You can turn analytics off. Feedback is sent only when you submit it.
One switch stops AI requests.
When Ray uses cloud AI, it sends your message and relevant context to Diorama's server and a secure Google AI service. Diorama does not keep readable prompt or response content after serving the request. Google does not use Diorama's data to train or fine-tune its models. It may cache parts of a request, encrypted, for up to 24 hours to speed up later requests, and may retain a prompt for up to 90 days if automated safety systems flag it for suspected abuse. Turn AI off and AI requests stop; analytics and other app features follow their own settings. See how Ray works.
Export and delete are yours.
You can export or delete local records in the app. You can also ask Diorama to delete feedback, entitlement, or other server-side records associated with you.
Founder philosophy
I'm a jaded Gen Xer who was raised by anti-establishment hippies. I think everyone is getting tired of surveillance society and our personal data being used to sell us stuff. My goal with Diorama is to share with you a fitness planning tool that is privacy-first.
Ray uses a sandboxed AI model for cloud requests. Google does not use Diorama's data to train or fine-tune its models. Your core records stay on your local device. Cloud services receive only the limited information described in the privacy policy when you use a connected feature. As server admin, I don't get to (or want to) see your core records unless you explicitly choose to share something.
