KoseFlow ("we", "our", "the extension") is a Chrome extension that automates image and video generation on Google Flow (labs.google). We are committed to protecting your privacy. This policy explains what data we collect, why we collect it, and how it is handled.
When you sign in with your Google account, we store the following information in our database (Firebase Firestore):
We do not collect, store, or transmit your generated images, video files, prompts, or any content you produce through Google Flow.
Sign-in is handled entirely through Google OAuth 2.0 via the Chrome Identity API. We never see or store your Google password. The OAuth token is used only to obtain your email address and authenticate your Firebase session.
Pro plan purchases are processed by LemonSqueezy (lemonsqueezy.com), a third-party payment provider. We do not collect, process, or store any credit card or payment information. When you activate a license key, the key is verified with LemonSqueezy's API and then discarded — only the resulting plan status (pro) is saved to your account.
We do not sell, rent, or share your personal data with any other third parties.
Your account data (email, plan, usage) is retained as long as you have an active account. You may request deletion of your data at any time by contacting us at the email below. Upon request, we will permanently delete your Firestore document within 7 days.
The extension uses Chrome's local extension storage to persist your UI settings (e.g., model selection, concurrent prompt count, filename prefix). This data never leaves your device and can be cleared by removing the extension.
The extension requests the following Chrome permissions:
KoseFlow is not directed at children under the age of 13. We do not knowingly collect personal information from children.
We may update this privacy policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the extension after changes constitutes acceptance of the updated policy.
