Tempo ("Tempo," "we," "us," or "our") is a business operations platform for small businesses. This Privacy Policy explains what data we collect, how we use it, and — importantly — what we don't do with it.
We only collect what's necessary to run the service:
You never paste API keys or secret credentials into Tempo. Here is exactly what is stored:
What this means for you: Payments from your clients go directly to your Stripe or Square account (or wherever your own payment link points). Tempo never holds your money and never has your Stripe or Square password.
We do not sell your data. We do not use your data for advertising. We do not share your data with third parties except as described in Section 5.
Tempo uses the following third-party processors. Your data may pass through their systems as part of providing the service:

Stripe

Tempo uses AI (powered by Anthropic's Claude) to draft proposals, review requests, follow-ups, and insights. No AI-generated content is ever sent automatically. Every draft requires your explicit review and approval before anything is sent.
AI drafts stored in our database are permanently deleted after you approve and send them, or when you dismiss them. We do not use your business data to train AI models.
We retain your data for as long as your account is active. When you delete your account:
You have the right to:
To exercise any of these rights, email us at [email protected]. We will respond within 30 days.
We take security seriously. All data is encrypted in transit (HTTPS). Database access is protected by row-level security — each user can only access their own data. API keys and credentials are never stored on our servers. However, no system is 100% secure. Use a strong, unique password and keep your browser credentials private.
Tempo is not intended for use by anyone under 18. We do not knowingly collect data from minors.
If we make material changes to this policy, we will notify you by email or via an in-app notice at least 14 days before the changes take effect. Continued use of Tempo after that date constitutes acceptance of the updated policy.
