TEMPO

Privacy Policy

TEMPO · D3 Hospitality · last updated 9 August 2026

TEMPO is a lifting app. It records what you lift so you can beat it next time. It does not have advertising, analytics, trackers, or any interest in your data beyond showing it back to you.

The short version

What TEMPO stores on your device

All of this stays on the device unless you create an account and link it:

What leaves your device, and only if you ask

If you create an account at tempostrength.com and pair a device, TEMPO syncs your training so it survives a lost or replaced phone. That sync covers your plans, sessions, sets, preferences, body measurements, goals, and any paired hardware.

Some things are deliberately never sent, even when you are signed in: how you arranged today's workout (lifts added, reordered, held back or dropped) and your motion calibration. Those live only on the device that made them.

Your account itself stores one piece of personal information: your email address, used to identify the account and nothing else. TEMPO does not email you marketing.

Sensor data

With motion features on, TEMPO reads the accelerometer in your glasses or phone to count reps. That raw sensor stream is processed on the device and is never transmitted or stored anywhere. What can be saved is the result — a rep count, and a depth figure attached to a set.

Who else is involved

ServiceWhat it doesWhat it sees
Supabase Stores your account and synced training Your email and the training data listed above — only if you make an account
Google "Continue with Google" sign-in That you signed in to TEMPO. TEMPO receives your email address and nothing else — no contacts, no Drive, no profile browsing
Google Fonts Serves the typeface Your IP address when a font loads, as with any site using Google Fonts
Vercel Hosts tempostrength.com Standard web server logs for the website
Stripe The optional "Support the dev" tip, on the web only Only what you type on Stripe's own checkout page. TEMPO sends Stripe nothing about you or your training, and never sees your card

On Even Realities G2, TEMPO runs inside the Even Realities app, which has its own privacy policy covering the glasses themselves. This policy covers TEMPO only.

What TEMPO does not do

Your data is yours

For anything else — a copy of what is held, a correction, a question — email ops@d3hospitality.com.

Your voice, and the AI coach

TEMPO COACH is optional and off unless you use it. When you dictate a question from the glasses, the microphone opens only when you choose “Ask the coach” and closes when you send or cancel. The audio is sent to our server, transcribed (via OpenAI's transcription API), and immediately discarded — the recording is never stored. The transcribed text and a summary of your training history are sent to OpenAI to produce your consultation; under the API terms this data is not used to train their models. Consult text is kept in your account's coach log so your history stays consistent across devices, and it is deleted with your account.

How long it is kept

Synced data is kept until you delete it or delete your account, because it is your training history and the point is that it lasts. Deleting the account removes it. Pairing codes are held for ten minutes and are stored only as a one-way hash, never in a readable form.

Security

Traffic is encrypted in transit. Synced rows are protected by row-level security so an account can only ever read and write its own data. TEMPO never stores your Google password — sign-in happens on Google's own pages.

Children

TEMPO is not directed at children under 13 and does not knowingly collect their data. If you believe a child has created an account, email the address above and it will be removed.

Changes

If this policy changes in a way that affects what is collected or who receives it, the date at the top changes and the change is described here.

Terms

Using TEMPO is also subject to the Terms of Service.
