Privacy Policy

Last updated September 30, 2026

Sentry Brain Single Member P.C. (“Sentry Brain,” “we,” “us,” or “our”) is responsible for the personal information processed through Sentry Driver and our website.

For privacy questions or requests, contact support@sentrydriver.app.

Account deletion

You can request deletion under Settings → Data & Privacy → Delete My Data, or by emailing support@sentrydriver.app from your account email.

An in-app request stops vehicle tracking and starts a 30-day recovery period. Signing in during this period cancels the request. After the period ends, we permanently delete your account and associated personal information, subject to the limited retention described below. After deletion we keep a minimal record that your request was carried out, without your email or other personal details. You can contact us to request erasure without the recovery period.

Deleting your account does not cancel subscriptions billed by Apple or Google.

Information we handle

We collect information you provide, information generated through use of our app and website, and vehicle and purchase information received from Tesla, Apple and Google. Depending on the features you use, this includes:

Account and contact information: name, email, account identifier, preferences, referrals and support messages.
Tesla connection information: credentials authorizing access to your connected vehicle. We do not receive your Tesla password.
Vehicle information: vehicle identifiers and status, precise location, trip history, driving events, charging and battery data, and monitoring preferences.
Device and technical information: device and notification identifiers, whether your registered phone appears present, IP addresses, performance information and crash reports.
Purchase information: subscription status and transaction records from Apple or Google. We do not receive payment-card details.
Analytics information: app and website activity and campaign attribution, subject to the choices described below.

Vehicle records relate to the connected vehicle; Sentry Driver does not identify who is driving. We do not receive Tesla cabin-camera footage.

Drivers of monitored vehicles

This section is for you if you drive a Tesla that someone else has connected to Sentry Driver: a family member’s car, a car you borrowed or rented, or a car handed to you as a valet.

While you drive, we record information about the vehicle: its location, speed, trips, and driving events such as speeding or hard braking measured against the rules the account holder has set. We do not record your identity and we collect nothing from your phone. Sentry Driver only estimates whether the account holder’s registered phone is present; it does not identify who is driving.

The account holder is the only person who sees this information. We process it on the basis of the vehicle owner’s legitimate interest in protecting their property and knowing how it is driven, and our legitimate interest in providing that service to them. Our Terms require the account holder to tell anyone they let drive the vehicle that it is monitored.

You can contact support@sentrydriver.app with questions or requests, including to object to this processing. Because we cannot tell who was driving, we may ask for information to identify the vehicle and relevant trips and verify that they relate to you. You can provide this information directly; the account holder does not need to participate if you provide sufficient information. We only disclose trips we can verify relate to you, and we take the rights of the vehicle owner and other drivers into account.

Why we use information

We use personal information on the following legal bases:

To provide our service: managing accounts, connecting vehicles, recording history, providing alerts, verifying subscriptions and handling support, as necessary to perform our contract with you.
To protect and maintain the service: securing accounts, preventing misuse and diagnosing faults, for our legitimate interests in operating a secure and reliable service.
To apply referral invitations: temporarily matching an invitation visit to a new account using a hashed IP address, for our legitimate interest in applying your chosen referral and crediting the inviter. This matching stays within our service and is not used for analytics or advertising.
To measure usage and campaigns: using optional app analytics with your consent, to improve the app and understand advertising effectiveness. Website analytics relies on your consent where requested, or on our legitimate interest in understanding visits and improving the website for visitors in the United States, as explained below.
To meet legal obligations: responding to privacy requests, maintaining required records and complying with applicable law. Information needed for a specific legal claim may also be retained for our legitimate interest in establishing or defending that claim.

Account and vehicle information needed for a requested feature is necessary to provide that feature. Optional analytics is not a condition of using Sentry Driver.

Who receives information and where

We do not sell personal information. We share information as needed with service providers, including Hetzner and Netlify for hosting; Firebase and Apple for notifications and app services; Resend for email; Freshdesk for support; and the analytics providers described below. Mapping providers receive requests needed to display maps and find addresses.

We also exchange information with Tesla for vehicle connectivity and Apple and Google for purchases and platform services. These companies process information for their own services under their respective privacy policies. Information may be disclosed to advisers or authorities where legally necessary.

Our main service data and backups are hosted by Hetzner in the United States. Freshdesk also processes our support data in the United States. Other providers may process information internationally. For processing outside the European Economic Area, we use applicable data-processing agreements and transfer safeguards, including Standard Contractual Clauses where required. Contact us for information about, or a copy of, the safeguards applicable to your data.

Your analytics choices

Optional app analytics uses Firebase Analytics for usage statistics and AppsFlyer for campaign measurement, including our Apple Ads campaigns. This involves app activity, including subscription events, and associated identifiers.

Both purposes are off by default. You can accept or decline them together, or choose each separately through Customize. You can change or withdraw either choice at any time under Settings → Privacy, without affecting your access to the service. Withdrawing a choice stops further collection for that purpose; you can contact us to request deletion of information already collected.

Our website uses Google Analytics to understand visits and traffic sources and improve the website. Outside the United States, or when the region cannot be determined, it requires prior acceptance. In the United States, it may be enabled by default on the basis of our legitimate interest in this limited audience measurement, subject to saved choices and applicable browser privacy signals. Google Signals and advertising personalisation are disabled. You can object to this measurement or change your choice at any time through Cookie settings in the footer, without affecting your access to the website.

How long we keep information

We retain account and vehicle history while providing the account and history-storage service, until deletion or the end of the relevant purpose. Other retention periods include:

Unused accounts: if you connect a Tesla account but never start a subscription, monitor a vehicle or record a drive, and do not open the app for 30 days, we automatically delete the account and everything stored with it. You can sign in again at any time to create a new one.
Support tickets: 24 months after closure.
Referral matching: the temporary matching record can be used for up to 30 minutes and is deleted as soon as the referral is applied. Unused records are deleted by the daily cleanup. The resulting referral relationship is kept with the accounts to manage the reward.
Backups: deleted information may remain in backups until they are overwritten, normally over a cycle of approximately one week.
Technical logs: retained for security and troubleshooting. The period varies by log type; web access logs are normally retained for about 14 days.
Google Analytics: retention is set to two months for event data and 14 months for user data, with the user period renewed by recorded activity. These limits do not apply to standard aggregated reports.
AppsFlyer: its published policy generally limits end-user analytics data to 24 months, subject to legal exceptions or specific retention instructions. Aggregated data may be retained for up to 25 months.

We retain information longer only where needed for a specific legal obligation or outstanding claim. Such retention is limited to the information and period needed for that purpose.

Security and your rights

We use access restrictions, protected communications and backup procedures to safeguard personal information.

Depending on applicable law, you may request access, correction, deletion, restriction or portability of your information, and object to processing based on legitimate interests. You may withdraw consent at any time; this does not affect the lawfulness of processing before withdrawal.

Contact support@sentrydriver.app to exercise your rights. We verify requests proportionately and normally respond to GDPR requests within one month. We will explain any lawful extension.

You may complain to your local data-protection authority. In Greece, this is the Hellenic Data Protection Authority.

Children

Sentry Driver accounts are intended for adults. We do not knowingly offer accounts to children.

Changes to this policy

We may update this policy to reflect changes to our service or privacy practices. The date above identifies the latest revision.
