Privacy Policy

Effective date: July 31, 2026

Echo Node is developed and operated by Fighting Gravity Software ("Echo Node," "we," "us," or "our"). This Privacy Policy explains how Echo Node handles information when you use the Android application and its optional cloud features.

Questions about this policy may be sent to jay@fgsw.dev.

THE SHORT VERSION

Echo Node is designed to work without an Echo Node account. Recordings and other user-created content remain on your device unless you choose a feature that sends data off the device, such as Gemini transcription, AI Summary, Google Drive backup, Google Play subscription verification, or sending a feedback email.

Echo Node does not sell personal information and does not use recordings, transcripts, notes, or summaries for advertising.

INFORMATION THAT REMAINS ON YOUR DEVICE

The following information is stored locally unless you choose an applicable cloud, backup, export, or sharing action:

• audio recordings;

• notes and timestamped notes;

• transcripts and transcript edits;

• AI summaries saved in the app;

• recording names and metadata;

• app settings; and

• voice profiles and voice embeddings used for local saved-voice recognition.

Local content remains on the device until you delete it, clear the app's storage, or remove the app in a way that deletes its data. You may also export or share content using Android's system sharing tools.

INFORMATION PROCESSED WHEN YOU USE OPTIONAL CLOUD FEATURES

### Gemini transcription

When you choose Gemini transcription, Echo Node sends an anonymous installation identifier and technical upload metadata to the Echo Node backend. Temporary decoded audio is then uploaded through a backend-authorized Google Gemini upload destination for transcription. Speaker labels or names you have chosen may be included when needed to produce or update the transcript.

Echo Node requests deletion of temporary processing files after the operation. The Echo Node backend does not persist the recording or completed transcript content.

### AI Summary

When you request an AI Summary, the selected transcript, confirmed speaker names, and any confirmed "This is me" identity needed for the requested result are sent through the Echo Node backend to Google Gemini. The Echo Node backend does not persist the transcript or completed summary content.

AI transcripts, speaker assignments, voice matches, and summaries can contain mistakes. Review important results against the original recording.

### Google Drive

Google Drive connection and backup are optional. If you connect Drive, Echo Node receives authorization to create and manage Echo Node backup files in the selected Google account. Echo Node may locally remember the connected account's email address so backup work remains associated with the correct account.

A Drive backup may include recording audio and a sidecar document containing associated Echo Node metadata or user-created content. You control whether Drive backup is used. Echo Node can move its Drive copies to trash and disconnect its access. Google may retain data according to your Google account settings and Google's policies.

### Google Play purchases

Echo Node uses Google Play Billing to sell and restore Premium access. Google processes payment details. Echo Node does not receive your full card or bank information. Echo Node and its backend process purchase history, purchase tokens, subscription state, billing periods, and entitlement records needed to verify access, restore purchases, prevent abuse, and maintain allowances.

### Tester access and feedback

Closed-test access codes are associated with tester-access and entitlement records. If you choose Settings > Email tester feedback, your email app prepares a message to Fighting Gravity Software. Echo Node includes basic diagnostic context such as app version, Android version, and phone model. Echo Node does not automatically attach recordings, transcripts, summaries, notes, or voice profiles.

TECHNICAL AND DIAGNOSTIC INFORMATION

Echo Node may process:

• a randomly generated anonymous installation identifier;

• app version, Android version, and device model;

• cloud-operation type, duration, allowance consumption, and counters;

• non-content status, latency, token-count, error, and service-health information;

• Google Play purchase and integrity verification results; and

• identifiers required by Google services for Drive, Billing, and Play Integrity.

This information is used to provide app functionality, operate Premium allowances, verify purchases, prevent fraud or abuse, diagnose failures, and maintain service reliability.

CATEGORIES OF INFORMATION COLLECTED

Depending on the optional features you use, Echo Node may collect or process:

• Personal information: chosen speaker names, a chosen self-name, connected Google account email, and service identifiers;

• Financial information: Google Play purchase and subscription history, excluding full payment-card or bank details;

• Audio files: recordings voluntarily submitted for Gemini transcription or Google Drive backup;

• Files and documents: optional Google Drive sidecar documents;

• App activity: cloud-feature interactions, notes, transcripts, speaker labels, summary inputs, usage counters, and non-content service telemetry;

• Diagnostics: error, status, latency, version, and service-health data; and

• Device or other identifiers: an anonymous installation identifier and Google service integrity or entitlement identifiers.

Echo Node does not collect precise or approximate location, contacts, calendar data, browsing history, photos, videos, health data, or messages as part of its current features.

HOW INFORMATION IS USED

Information is used only as reasonably necessary to:

• record, organize, transcribe, summarize, back up, restore, export, and play user content;

• verify Premium access and enforce purchased allowances;

• operate local and cloud features selected by the user;

• recognize saved voices locally after user confirmation;

• maintain security and prevent fraud or abuse;

• diagnose errors and improve reliability; and

• respond to support or tester feedback initiated by the user.

SERVICE PROVIDERS

Echo Node uses service providers to perform functions on our behalf, including:

• Google Gemini / Google Cloud for optional AI transcription, summaries, and backend infrastructure;

• Google Drive for optional user-controlled backups;

• Google Play Billing for purchases and subscription management; and

• Google Play Integrity for installation, purchase, and abuse-prevention checks.

These providers process information under their applicable terms and privacy policies. Echo Node does not sell user data or provide it to data brokers.

SECURITY

Data sent between Echo Node, the Echo Node backend, and Google services is encrypted in transit using secure network connections. No system can be guaranteed completely secure. You are responsible for protecting access to your device, Google account, exported files, and backups.

RETENTION

• Local recordings and user-created content remain until you delete them or clear app data.

• Google Drive backups remain under your control and Google's applicable retention practices.

• Temporary Gemini audio is used for processing, and Echo Node requests deletion after the operation.

• The Echo Node backend does not persist recordings, transcript content, or summary content.

• Cloud operational records are retained only for service operation, security, billing, and troubleshooting. Current configured periods include approximately 45 days for usage records, up to 400 days for inactive entitlement and commercial-balance records, 90 days after expiration for tester-code records, and 2 days for Gemini dispatch records.

• Google Play and Google Drive may retain information under your relationship with Google and their applicable policies.

YOUR CHOICES

You can:

• use local recording and On-Device transcription without Gemini;

• decline or stop using Premium cloud features;

• connect or disconnect Google Drive;

• delete local recordings, notes, transcripts, summaries, and voice profiles in the app;

• trash Echo Node backup copies from Drive; and

• manage or cancel a Premium subscription through Google Play.

Echo Node does not currently create user accounts and does not currently provide an automated request mechanism for deleting pseudonymous backend operational records. Privacy questions may be sent to jay@fgsw.dev.

RECORDING RESPONSIBILITY

Recording, consent, and notification laws vary by location and situation. You are responsible for obtaining any permission required by applicable law and for using recordings appropriately.

CHILDREN

Echo Node is intended for adults and is not directed to children under 18. We do not knowingly design the service to collect personal information from children.

CHANGES TO THIS POLICY

We may update this Privacy Policy when features, service providers, legal requirements, or data practices change. The effective date above will be updated when a revision is published.
