📄 Privacy Policy – Solace

Last updated: October 12, 2025

At Solace, privacy is fundamental to everything we do. We only collect what's necessary to deliver your personalized morning briefing. This policy explains what information we access, how we handle it, and how you maintain complete control.

🔐 What Information We Access

We access only what's needed to create your morning briefing. Here's what the app uses:

📬 Email Summary

What: Subject lines, sender names, and email summaries

Why: To give you a quick snapshot of important emails

Source: Gmail or your connected email service via secure OAuth

Stored? No. Information is retrieved on-demand and not retained or shared.

💬 Slack Summary

What: Recent direct messages

Why: To surface important messages you may have missed

Source: Slack via OAuth authentication

Stored? No. Messages are processed temporarily and immediately discarded.

📅 Calendar Events

What: Your scheduled meetings and events for today

Why: To help you plan and prepare for the day ahead

Source: Google Calendar via secure API

Stored? No. Calendar data is only accessed when generating your briefing.

☀️ Weather & Commute

What: Current location, home and work addresses

Why: To calculate travel time and provide local weather conditions

Stored? Location is used only during briefing generation. Addresses are encrypted on your device.

📰 News Summary

What: News headlines matching your interests

Why: To keep you updated on topics that matter to you

Source: News APIs filtered by your topic preferences

Stored? No. News content is retrieved fresh each time.

🔒 Google API Services

Solace's use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

What this means for you:

• We only use your Google data to provide features in the Solace app

• We do not use your Gmail or Calendar data for advertising

• We do not sell or share your Google data with third parties

• We do not allow humans to read your data except with your explicit permission for support purposes

AI Processing & Data Training:

While we use AI to generate personalized summaries of your briefing content, we:

• Only use AI for personalization specific to your briefings

• Do not use your Google data to train general AI models

• Do not share your data with AI service providers beyond what's necessary to generate your briefing

• Process your data in compliance with Google's Limited Use requirements

Third-Party Services:

To generate your briefing, we share your data with these services:

• ChatGPT (OpenAI) - Processes calendar and email data to generate summaries

• ElevenLabs - Converts text summaries to audio speech

• Cloudinary - Mixes audio with background music

These services process your data only to provide the briefing feature and do not store your data permanently. We have agreements in place to ensure these services comply with Google's Limited Use requirements.

Human Access to Your Data:

Solace team members do not access your Google Calendar or Gmail data under normal circumstances. We may access your data only in these limited situations:

• You explicitly request support that requires viewing your data

• Required for security purposes (e.g., investigating abuse)

• Required by law or legal process

In all cases, we will request your explicit permission before accessing your data.

🔒 Data Protection & Security Measures

Solace implements multiple layers of security to protect your Gmail and Calendar data:

Encryption in Transit:

All data transmission uses TLS 1.3 encryption

Communication with Google APIs uses HTTPS with certificate validation

API requests secured with OAuth 2.0 bearer tokens

Encryption at Rest:

OAuth tokens encrypted using AES-256 before database storage

Database connections use SSL/TLS encryption

Infrastructure hosted on Supabase with industry-standard encryption

Access Controls:

OAuth tokens stored with user-specific access controls

Server-side validation prevents cross-user data access

JWT authentication required for all API requests

Team members cannot access your data without explicit permission

Data Retention:

OAuth tokens stored only as long as needed for briefings

Email and calendar content fetched on-demand, immediately discarded after processing

You can revoke access anytime through Google Account settings or the app

Upon account deletion, all OAuth tokens are immediately removed

Data Minimization:

We request only minimum necessary scopes: email, profile, read-only Gmail and Calendar

No write access to your Gmail or Calendar

Only data necessary for briefings is processed

Third-Party Processing:

AI processing (Wordware) and text-to-speech (ElevenLabs) services process data in memory only

Third-party services do not permanently store your Google data

Data processing agreements ensure compliance with Google's Limited Use requirements
