Tally stores the account details, profile, goals, foods, diary entries, weights, and optional exercise totals you choose to sync. This data is linked to your account only so Tally can provide its features across your devices and connected assistants.
Health data stays on your device unless you explicitly enable Health cloud sync. Tally does not sell personal data, use it for advertising, or track you across apps and websites.
You can revoke assistant access or permanently delete your account and synced data from the account page. Contact support for privacy questions.
