Privacy Policy

Effective 31 May 2026

This Privacy Policy explains how SentinelMDM (“SentinelMDM,” “we,” “us”) collects, uses, protects, and shares information when you use our website, software, and services. By creating an account or using the service you agree to this policy.

1 · Who we are

SentinelMDM provides disclosed, consent-based parental-control and mobile device management (MDM) software on a subscription basis, with optional pre-configured hardware. Questions about this policy or your data can be sent to [email protected].

2 · Information we collect

  • Account information — a username and email address you provide at registration.
  • Billing information — handled by our payment processor, Stripe. We do not store or see your full card number; we keep only a subscription reference and order metadata.
  • Device data you choose to collect — when you enroll a device you own and administer, the agent captures the telemetry you enable (e.g. location, screen time, app activity, and other signals). This data is encrypted on the device before it is sent (see §3).
  • Technical data — basic operational metadata (device identifiers, app version, connection status, IP address) used to run the service, secure it, and provide support.

3 · Zero-knowledge encryption

SentinelMDM is a zero-knowledge system. Private device telemetry is encrypted on the device before transmission and can only be decrypted in the account owner's browser using a key derived from your password. We physically cannot read your private device data — our servers store opaque ciphertext. Because the key never leaves you, we also cannot reset your password or recover your encrypted data if you lose it.

4 · How we use information

  • To provide, maintain, and secure the service and your account.
  • To process subscriptions, trials, and payments through Stripe.
  • To send transactional messages (account approval, billing, support replies).
  • To comply with law and prevent fraud or abuse.

We do not sell your personal information, and we do not use your encrypted device data for advertising.

5 · Sharing & service providers

We share information only with service providers who help us run the service — principally Stripe (payments) and our hosting/infrastructure providers — and only as needed to provide it. We may disclose information if required by law or to protect our rights and users. We never sell data to third parties.

6 · Data retention

Captured device telemetry and binary objects automatically purge on a 30-day TTL. We retain account and billing records for as long as your account is active and as required for legal, tax, and dispute-resolution purposes. You can delete your account and its encrypted data at any time (see §8).

7 · Children & COPPA

SentinelMDM FamilySafe is intended for a parent or legal guardian to supervise their own family member on a device the parent owns and administers, with monitoring disclosed to the device user. The account holder is the adult parent/guardian, who provides any consent required under the Children's Online Privacy Protection Act (COPPA) and applicable law. The service is not directed to children for independent sign-up, and we do not knowingly collect data from a child as a standalone user.

8 · Your choices & rights

9 · Security

We protect data with end-to-end encryption, hardware-backed device keys, encrypted-at-rest storage, and strict access controls. No system is perfectly secure, but the zero-knowledge design means that even a server compromise does not expose your readable private data.

10 · Cookies

We use strictly necessary cookies and similar storage to keep you signed in and operate the dashboard. We do not use third-party advertising or cross-site tracking cookies.

11 · Changes & contact

We may update this policy; material changes will be posted here with a new effective date. Questions? Email [email protected].
