Terms and Conditions

Last updated: October 4, 2026

1. Description of Service

SpeedMark is a mobile application that shows the posted speed limit in real time, warns you when you go over it, and keeps a tamper-evident record of your recent driving that you can replay and export. SpeedMark also provides optional Guardian Alerts that notify people you trust when you drive far over the limit or stop suddenly, without providing real-time location tracking or surveillance.

Key Features

• Real-time speed limits and escalating warnings
• Guardian Alerts (optional). Being a guardian is free; inviting guardians requires a paid plan that includes it (currently Full)
• Verified record of your recent driving, with replay and export in multiple formats (such as PDF, CSV, JSON, and GPX)
• Privacy-first design with local data storage

2. Eligibility and Account

You must be at least 16 years old to use SpeedMark. By using the app, you represent that you meet this age requirement and have the legal capacity to enter into these terms. Guardian features require you to sign in and provide your name and email address.

3. Acceptable Use

Permitted Uses

• Using SpeedMark for speed awareness, safety, and keeping a record of your own drives
• Exporting your own speed data for legitimate purposes
• Using the app in compliance with local traffic and privacy laws

Prohibited Uses

• Using the app while driving in a manner that causes distraction
• Using exported data to make false claims or commit fraud
• Sharing or selling your exported data to unauthorized third parties

⚠️ Important Safety Notice
Never interact with SpeedMark while actively driving. The app is designed to work automatically in the background. Your safety and the safety of others is paramount.

4. Data and Privacy

Your privacy is important to us. Please review our Privacy Policy for detailed information about how we collect, use, and protect your data.

Key Privacy Points

• Your speed and location records are stored on your device, not on our servers
• The app keeps the last 2 minutes of each session; sessions you don't save are deleted automatically
• Your data is never sold to third parties
• You maintain full control over your data export and deletion
• Guardian alerts share only speed, speed limit, street name, and time, not routes or live location

5. Guardian Alerts

SpeedMark's Guardian Alerts allow drivers to designate trusted contacts who receive notifications when the driver exceeds the speed limit by 20% or more, or comes to a sudden stop from speed. Being a guardian is free. Inviting guardians requires a paid plan that includes this feature.

How Guardian Alerts Work

• Drivers must explicitly invite guardians via the app
• Guardians receive alerts only when alert thresholds are met
• Guardians do NOT receive real-time location tracking
• Guardians cannot view driving routes or destinations, and see only the alerts you trigger
• Drivers can revoke guardian access at any time

Guardian Responsibilities

• Guardians agree to use alerts only for safety purposes
• Guardians must respect driver privacy and not misuse alert information
• Guardians acknowledge that alerts are for informational purposes only

Driver Consent and Control

• Guardian features require explicit driver consent
• Drivers control who receives alerts
• Drivers can disable guardian alerts at any time without notice
• No guardian data is shared without driver permission

⚠️ Guardian Alert Limitations
Guardian alerts are provided as a safety tool but do not guarantee accident prevention or driver safety. Alerts may be delayed or not delivered, for example because of poor GPS signal, no network connection, disabled notifications, or device limitations. SpeedMark is not responsible for driver behavior or outcomes related to guardian notifications. Guardians should use alerts as a conversation tool, not as a surveillance mechanism.

6. Speed Limit Information and Advisory Use

SpeedMark's speed limits come from third-party map data and may be incomplete, out of date, or wrong. This includes construction zones, temporary or variable limits, school zones, and recently changed roads. Warnings and alerts are advisory only. The posted signs and the law always control.

You remain solely responsible for obeying traffic laws, for watching the road, and for driving safely. SpeedMark is an independent app. It is not a certified in-vehicle Intelligent Speed Assistance (ISA) system and does not replace your attention or judgment. Warnings may be delayed or missed, for example because of GPS limits, loss of network connection, battery or operating-system restrictions, or notification settings.

7. Accuracy and Legal Disclaimer

No Guarantee of Legal Outcome

While SpeedMark uses GPS technology and cryptographic verification to create a tamper-evident record, we cannot guarantee that a record will be accepted in any legal, insurance, or other proceeding. Admissibility varies by jurisdiction, court, and specific circumstances.

GPS Accuracy Limitations

• GPS accuracy can be affected by weather, buildings, tunnels, and other environmental factors
• Reported accuracy is typically 3-10 meters in optimal conditions
• SpeedMark provides the best available data but cannot account for all variables
