Privacy Policy
Last updated: April 2026
The short version
Continuum Writer is a local-first desktop app. Your manuscripts, characters, timelines, and all creative data stay on your machine. We never see it, collect it, or have access to it.
1. What data the App collects
None. Continuum Writer does not send any data to our servers. All your work is stored in local files on your device.
When you use AI features, queries are sent directly from your device to your chosen provider (OpenAI, Anthropic, or a local model). We are not involved in this communication and do not have access to the content of your queries or responses.
2. What data the website collects
Our website uses privacy-friendly analytics that do not use cookies and do not collect personal data. We see anonymous aggregate data only: page views, referral sources, and country. We cannot identify individual visitors.
3. Email & waitlist
If you sign up for our waitlist or email updates, we store your email address with our email provider (Kit / ConvertKit). You can unsubscribe at any time. We do not share your email with third parties.
4. Purchases
Purchases are processed by Lemon Squeezy, our payment provider. They handle your payment information. We receive your name, email, and license key — we do not receive or store credit card details.
5. License validation
When you enter a license key in the App, it validates directly with the Lemon Squeezy API. This requires an internet connection. The only data transmitted is your license key for verification. The validation result is cached locally.
6. API keys
API keys you enter in Continuum Writer (for OpenAI, Anthropic, etc.) are stored locally on your device. They are never sent to our servers. In a future update, they will be stored in your operating system’s secure keychain.
7. Children
Continuum Writer is not directed at children under 13. We do not knowingly collect data from children.
8. Changes
We may update this policy from time to time. The latest version will always be available at this URL.
