Privacy Policy
NinjaWatcher (“we,” “our,” or “us”) is committed to protecting your family's privacy. This policy describes what data we collect, how we use it, and your choices.
1. Information we collect
1.1 Account information
When you create an account, we collect your email address, a display name (if you provide one), and a hashed password. We use this to authenticate you, manage your subscription, and communicate with you about your account.
1.2 Subscription and payment information
If you subscribe to a paid plan, payment processing is handled by Stripe. We store your plan type, subscription status, and billing period. We do not store your full credit card number; Stripe does. Stripe's privacy policy applies to payment data: stripe.com/privacy.
1.3 Product usage and device data
We may collect aggregated, anonymized usage data (e.g., which features are used, app version, device type) to improve the product and fix issues. We do not log or store the content of web pages, search queries, or images that are filtered. Filtering happens on your device; we do not receive that content.
1.4 Support and communications
If you contact support or send us email, we keep a record of that correspondence to assist you and improve our service.
2. What we do not do
- We do not keylog, record keystrokes, or capture screenshots.
- We do not upload raw web content, images, or browsing history to our servers for filtering. Filtering runs locally on your device.
- We do not sell your personal data to third parties.
- We do not use your data for advertising or cross-site tracking.
3. How we use your information
We use the information we collect to:
- Provide, maintain, and improve the NinjaWatcher service
- Process your subscription and manage billing
- Send you important account or security notices
- Respond to your support requests
- Comply with applicable law and protect our rights
4. Data retention and deletion
We retain your account and subscription data for as long as your account is active. If you close your account, we will delete or anonymize your personal data within a reasonable period, except where we must retain it for legal or legitimate business purposes (e.g., tax records).
You may request deletion of your account and associated data at any time by contacting us at privacy@ninjawatcher.com.
5. Security
We use industry-standard security practices to protect your data, including encryption in transit (TLS) and at rest where applicable. Passwords are hashed; we never store plaintext passwords. We limit access to personal data to those who need it to operate the service.
6. Children's privacy
NinjaWatcher is intended for use by parents or guardians to protect minors. We do not knowingly collect personal information directly from children under 13. Accounts are created and managed by adults. If you believe a child has provided us personal information without parental consent, please contact us and we will delete it.
7. Cookies and similar technologies
We use cookies and similar technologies for authentication, session management, and security. For details, see our Cookie Policy.
8. Third-party services
We use the following third-party services. Each has its own privacy policy:
- Supabase — authentication and database hosting
- Stripe — payment processing
- Vercel (or similar) — hosting of our website
We do not share your personal data with third parties for their marketing purposes.
9. International data and your rights
Our services may be accessed from different countries. Data may be processed in the United States or other jurisdictions where our service providers operate. If you are in the European Economic Area, UK, or certain other regions, you may have rights to access, correct, delete, or port your data, or to object to or restrict processing. To exercise these rights, contact us at privacy@ninjawatcher.com.
California residents: We do not sell personal information. For more on your California privacy rights, contact us at the email above.
10. Changes to this policy
We may update this Privacy Policy from time to time. We will post the updated policy on this page and update the “Last updated” date. If changes are material, we may notify you by email or through the product. Continued use of NinjaWatcher after changes constitutes acceptance of the updated policy.
