Privacy Policy
Last updated: 7/11/2026
1. Introduction
StayInSync ("we", "us") provides an AI-powered email digest service delivered over WhatsApp. This policy explains what data we collect, why we collect it, and how we protect it.
2. Data we collect
- Account data: your name, email address, and WhatsApp number.
- Mailbox access tokens: OAuth tokens for Gmail / Outlook accounts you connect. We never see or store your email password.
- Email metadata & content: we read incoming messages from connected inboxes solely to filter and summarise them for your digest.
- Digest history: the summaries we generate are stored so you can review past digests.
3. How we use your data
Your data is used only to operate the service: classifying emails, generating your daily digest, and delivering it on WhatsApp. We do not sell your data, and we do not use the content of your emails to train third-party AI models.
4. Third-party services
We rely on Google (Gmail API), Microsoft (Outlook API), Meta (WhatsApp Business API), and AI model providers to deliver the service. Each processes data strictly to fulfil your digest request.
5. Google User Data
StayInSync accesses Gmail data solely to read and summarise emails for the authenticated user. We do not store, share, sell, or transfer Gmail data to any third party. Access is read-only and can be revoked at any time from the dashboard.
6. Data retention & deletion
You can disconnect any inbox or delete your account at any time from the dashboard. On deletion, your tokens, digest history, and profile are removed within 30 days.
7. Security
Tokens and personal data are encrypted at rest. Access is restricted to the systems that generate and deliver your digest.
