Terms of Service

Last updated: March 2026

These terms govern your use of Tagmux ("the Service"), operated by Tagmux ("we", "us"). By installing the Tagmux Shopify app or using the Tagmux API, you agree to these terms.

What the Service does

Tagmux receives event data from your store (via Shopify webhooks or our JavaScript SDK) and forwards it to advertising platforms you configure, such as Meta Conversions API, Google Ads, TikTok Events API, and others. We act as a data processor on your behalf.

Your responsibilities

• You must have a lawful basis to collect and process customer data in your jurisdiction
• You are responsible for obtaining any required customer consent before sending data through Tagmux
• You must configure your destinations with valid credentials that you are authorized to use
• You must keep your write key and webhook tokens confidential

Our responsibilities

• We forward events to your configured destinations reliably, with automatic retries on transient failures
• We hash customer PII (email, phone) with SHA-256 before sending it to ad platforms
• We encrypt stored credentials with AES-256-GCM and delete them when you remove a destination
• We do not sell, share, or use your event data for any purpose other than forwarding it to your destinations
• We respond to Shopify's mandatory GDPR webhooks and delete your data on app uninstall

Service availability

We aim to keep Tagmux available at all times but do not guarantee uninterrupted service. Events that fail to deliver are retried up to 5 times with exponential backoff. Delivery jobs are automatically pruned after 24 hours.

Limitation of liability

Tagmux is provided "as is". We are not liable for missed conversions, incorrect attribution, or any indirect damages arising from the use of the Service. Our total liability is limited to the fees you paid in the 12 months preceding the claim.

Termination

You may stop using Tagmux at any time by uninstalling the Shopify app or deleting your account. We may suspend or terminate your access if you violate these terms or use the Service to process data in violation of applicable laws.

Changes to these terms

We may update these terms from time to time. Material changes will be communicated via the email associated with your account. Continued use of the Service after changes constitutes acceptance.
