General
Privacy & data governance
Data retention policy
Tone retains Customer Data in accordance with our Privacy Policy. We retain aggregated statistics (e.g., tone analysis counts, improvement rates, user preferences) while your account is active. We do NOT store actual message content - messages are analyzed in real-time and only aggregated metrics are saved. Upon account deletion request, all Customer Data is permanently removed within 30 days. Inactive accounts (no activity for 12 months) may have data archived or deleted. Users can request data deletion at any time by contacting privacy@checktone.app.
Data archiving and removal policy
Tone will remove Customer Data in accordance with GDPR and user requests. Upon account deletion request, we permanently delete all user data from our database including: user profiles, preferences, aggregated statistics, and OAuth tokens (Slack and Google Calendar). Data removal is completed within 30 days of request. Users can request deletion by contacting privacy@checktone.app. We do not archive Customer Data after deletion. Message content is never stored, only aggregated statistics which are deleted with the account.
Data storage policy
Tone stores Customer Data in accordance with industry-standard security practices. We store only aggregated statistics (NOT message content) in a PostgreSQL database hosted on Supabase. All data is encrypted at rest. We use secure OAuth tokens for Slack and Google Calendar integrations, stored encrypted in the database. Data is stored only for the duration of active account use. Users can request data export or deletion at any time. We comply with GDPR requirements for EU users.

Certifications & compliance
Data deletion request procedure
