SynapX ("we", "us", "our") is the developer and publisher of the SynapX mobile application available on the Apple App Store. For privacy-related questions, contact us at: privacy@synapx.app
SynapX uses Sign in with Apple for authentication. When you sign in, we receive and store on our backend:
The notes you create — including text, titles, tags, categories, imported content, transcribed voice notes, and Vault (private) notes — are stored locally on your device in the app's storage. Your notes are not uploaded to or stored on our servers. They remain on your device unless you choose to export or back them up yourself, and they are removed when you delete the App.
SynapX offers optional AI features (auto-organization and the "Ask" assistant). These features require an internet connection. When you choose to process a note with AI or send a message to the assistant, the following is transmitted through our Supabase Edge Function to a third-party AI provider that generates the result:
Notes you mark as Private are never sent to the AI. Content sent for AI processing is used only to generate your requested result and is not stored on our servers beyond what is needed to complete the request. The AI provider may process request data under its own API data-processing terms and safeguards.
If you use voice capture, the app requests permission to access your device microphone and Apple's speech recognition. Voice input is converted to text using Apple's Speech framework. The resulting text is stored locally as a note and is only sent to AI if you subsequently choose to process it (see Section 2.3). We do not record or store raw audio on our servers.
With your permission, you can import images and documents from your camera or photo library. Text recognition (OCR) is performed on your device using Apple's Vision framework — image content is not sent to our servers for OCR. SynapX does not collect, use, or store your location.
The secure Vault uses Apple's local authentication (Face ID, Touch ID, or device passcode) to unlock private notes. Authentication is handled entirely by iOS on your device. We never receive or store your biometric data.
With your permission, SynapX schedules local notifications (e.g., reminders for scheduled items). Notification data is processed entirely on your device and does not involve transmitting information to our servers.
We do not sell your data. We do not show advertisements. We do not use third-party analytics or tracking SDKs.
Your notes, Vault contents, and app preferences are stored locally on your device and are removed when you delete the App.
Your Apple User ID, optional name, email, and a last-updated timestamp are stored in our Supabase database to maintain your account profile. This data is retained for as long as your account exists.
When you delete your account from the Profile screen in the App, we send a deletion request to our backend, which permanently removes your profile record. Deleting the App also removes all locally stored notes and data from your device.
We use the following third-party services, each of which has its own privacy policy:
We do not share your personal data with any other third parties.
SynapX is a general productivity application and is not directed to children under the age of 13. The app does not knowingly collect personal information from children under the age of 13 beyond what is required for the Sign in with Apple flow. If you are a parent or guardian and believe your child under 13 has provided personal information through the app, please contact us at privacy@synapx.app and we will promptly delete that information.
Depending on your location, you may have the following rights:
EU/EEA/UK users (GDPR): You have additional rights including the right to object to processing and to lodge a complaint with your supervisory authority. Our legal basis for processing is your consent and our legitimate interest in providing the service.
California users (CCPA): We do not sell personal information. You have the right to know what personal information we collect and the right to deletion as described above.
No method of electronic storage or transmission is 100% secure. In the unlikely event of a data breach involving your personal information, we will notify you as required by applicable law.
Our backend infrastructure and the third-party AI service may be located in the United States or other countries. By using SynapX's AI features, you consent to the transfer of the relevant data to these locations. We ensure that appropriate safeguards are in place in accordance with applicable data protection laws.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page and, where required by law, notify you through the app. Continued use of SynapX after changes take effect constitutes acceptance of the revised policy.
If you have any questions, concerns, or requests regarding this Privacy Policy or your personal data, please contact us:
