Terms of Service

Last updated: 9 July 2026

These terms govern your use of TachoAssist ("the service"), a browser-based tachograph analysis tool operated by TachoAssist ("we", "us"). By creating an account or using the service you agree to these terms.

1. The service

TachoAssist lets you upload digital tachograph files (driver-card and vehicle-unit .DDD files), review the recorded activity, receive automated rule checks and generate reports. The service supports compliance work — it does not replace it.

2. Accounts and workspaces

• You may register as an individual driver (a personal workspace) or on behalf of a company (a company workspace). You must provide accurate information and keep your credentials secure.
• If you register on behalf of a company, you confirm you are authorised to bind that company to these terms.
• The account owner controls the workspace, its data and its billing.

3. Trial, plans and payment

• New workspaces start with a 14-day free trial. No payment card is required for the trial, and each workspace gets one trial only.
• Paid plans (Solo, Starter, Professional, Fleet) are monthly subscriptions billed through our payment provider, Stripe. Prices are shown at the point of purchase.
• Each plan includes a maximum number of drivers. You can change or cancel your plan at any time through the billing portal; cancellation takes effect at the end of the paid period.
• When the trial ends without a subscription, or a subscription lapses, the account becomes read-only: existing data and reports stay accessible and deletable, but new uploads, analyses and reports require a subscription.

4. Your data

• Tachograph files and the data derived from them remain yours. We process them solely to provide the service — see the privacy policy.
• Uploaded files are retained securely and can be deleted at any time in Settings. You can configure an automatic retention period; UK operators are responsible for keeping tachograph records for the legally required period (at least 12 months).
• You must only upload files you are lawfully entitled to process.

5. Acceptable use

You must not misuse the service — including attempting to access other users' data, disrupting the service, reverse-engineering it, or using it for unlawful purposes. We may suspend accounts that breach these terms.

6. Compliance disclaimer

Automated analysis can contain errors and rule interpretations can change. TachoAssist's output is an aid, not legal advice and not a definitive statement of compliance. You remain responsible for your own regulatory obligations, and should verify findings before acting on them.

7. Availability and liability

The service is provided "as is". We work to keep it available and accurate but do not guarantee uninterrupted operation. To the maximum extent permitted by law, our liability arising from the service is limited to the amount you paid us in the twelve months before the claim. Nothing in these terms limits liability that cannot be limited by law.

8. Changes

We may update the service and these terms. If we make material changes we will notify account owners by email or in the app before they take effect. Continued use after changes take effect constitutes acceptance.

9. Termination

You can delete your data and stop using the service at any time. We may terminate accounts for breach of these terms. On termination we delete workspace data in line with the privacy policy.

10. Contact and governing law

Questions about these terms: contact@tachoassist.com. These terms are governed by the laws of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
