Privacy Policy

Effective: February 2026  •  Last Updated: September 6, 2026

Introduction

Assembly Labs, LLC ("we," "us," or "our") operates the TOMO mobile application. This Privacy Policy explains how we collect, use, store, and protect your personal information when you use TOMO.

We believe in transparency. This policy is written in plain language so you can understand exactly what happens with your data.

What Data We Collect

Information You Provide

Information Collected Automatically

How We Use Your Data

Voice Data

When you use the voice logging feature:

  1. Your audio is recorded on your device
  2. The recording is sent to AssemblyAI, our transcription partner, for processing
  3. The transcript is returned and stored as structured text in your training journal
  4. The original audio file is stored privately in your account and accessible only to you

AssemblyAI processes your audio solely for the purpose of transcription and does not retain it beyond their processing window. See assemblyai.com/legal/privacy-policy for details.

AI Processing

TOMO uses Anthropic's Claude to read your training entries and write your coaching insights. Two things are worth being specific about, because they are easy to assume otherwise:

  1. What is sent is not anonymous. To make coaching personal rather than generic, TOMO sends a training profile alongside your session content. That profile includes your first name, belt and stripes, age, gender, body weight if you provided it, your gym, your training patterns, and any coach or instructor names that appear in entries you wrote.
  2. It includes injury information. If you mention injuries in your sessions, TOMO tracks which body parts recur and over what period, and sends that history so your coaching can account for it. This is training context, not medical record-keeping, and TOMO does not provide medical advice.

Anthropic processes this content to generate your insight and does not train its models on it — their commercial terms state that Anthropic may not train models on customer content. TOMO does not sell this data or share it with anyone beyond the processors listed below. If you would rather your entries were not processed this way, the AI features are the core of the app, so the practical option is not to use TOMO. See anthropic.com/legal/commercial-terms for details.

Data Sharing

We do not sell your personal data. Period.

We share data only in these circumstances:

Third-Party Services

TOMO uses the following services to operate:

Service Purpose Data Shared
Supabase Database hosting and authentication Account info, profile data, training logs
AssemblyAI Voice-to-text transcription Audio recordings (temporary, transcription only)
PostHog Usage analytics, so we can see where the app is confusing Screen names, a small number of named actions, your account id and email. Never your notes, transcripts, body weight, date of birth, gender or injuries. Not sold, not shared with advertisers, not used to track you across other apps or websites.
Sentry Crash reporting and error monitoring Error logs, device info, your email address, app state at time of crash, and the masked error replay described above. If you choose to send feedback by shaking the phone, the message, your name and belt, and a screenshot of the current screen. Nothing else is sent while the app is working normally.
Anthropic (Claude) Turning voice transcripts into structured sessions, and writing your coaching insights Session transcripts and journal content, plus a training profile containing your first name, belt and stripes, age, gender, body weight (if provided), gym name, training patterns, injury history, and any coach or instructor names that appear in your entries
Apple and RevenueCat Processing and tracking a TOMO Pro subscription, when one is offered in your version of the app Apple handles payment and holds your card details; we never see them. RevenueCat receives an anonymous customer identifier linked to your account and your subscription status (active, trial, expired).

Data Storage and Security

While we take reasonable measures to protect your data, no system is 100% secure. We cannot guarantee absolute security.

If Your Data Is Ever Compromised

If we become aware of a data breach in which your personal information collected through TOMO has been accessed, disclosed, or used without authorization, we will notify you, in accordance with applicable law, by email at the address on your account and through a notice in the app.

Your voice recordings and their transcripts are the most sensitive data TOMO holds. They are treated as in scope for this commitment in every case.

Your Rights

Data Retention

Children's Privacy

TOMO is intended for adults. The app is not directed to anyone under the age of 18, and we do not knowingly collect personal information from anyone under 18. If you believe someone under 18 has provided us with personal information, contact us at the email below and we will delete it promptly.

Changes to This Policy

We may update this Privacy Policy to reflect changes in our practices, technology, or legal requirements. When we make significant changes, we will notify you through the app or via email. Your continued use of TOMO after changes are posted constitutes acceptance of the updated policy.
