Data Processing Addendum

This addendum describes DirectSnail’s obligations when it processes customer personal data on a Shopify merchant’s behalf.

This Data Processing Addendum (“DPA”) is incorporated into the DirectSnail Terms of Service between the Shopify merchant using DirectSnail (“Merchant”) and DirectSnail. It applies when DirectSnail processes Personal Data for the Merchant.

1. Definitions and roles

“Data Protection Law” means privacy and data-protection laws applicable to the processing, including the GDPR where applicable and United States state privacy laws. “Personal Data,” “process,” “controller,” “processor,” “business,” and “service provider” have the meanings given by applicable Data Protection Law.

The Merchant is the controller or business for its customer Personal Data. DirectSnail is the processor or service provider and will process Personal Data only on the Merchant’s documented instructions, including instructions communicated through configuration and use of the service.

2. Processing details

Subject matterCreating, addressing, printing, delivering, suppressing, tracking, and measuring merchant-directed postal campaigns.
DurationFor the term of the Merchant’s use of DirectSnail and the limited retention periods needed to provide the service, honor suppressions, meet legal obligations, and complete deletion.
PeopleMerchant personnel, Shopify customers selected or evaluated for campaigns, postcard recipients, and people making support or opt-out requests.
Personal DataNames, postal addresses, Shopify customer identifiers, limited purchase attributes used for segmentation, campaign membership, postal delivery events, and order-attribution records.
PurposeProviding DirectSnail according to Merchant instructions. DirectSnail does not sell Personal Data or use it for cross-merchant advertising or profiling.

3. DirectSnail obligations

DirectSnail will:

  • Process Personal Data only to provide the service, comply with documented lawful instructions, or meet a legal obligation.
  • Not sell or share Personal Data for cross-context behavioral advertising; retain, use, or disclose it outside the business purposes in this DPA; or combine it with personal data received from another business except as permitted by law to provide the service.
  • Ensure personnel with access are subject to appropriate confidentiality obligations.
  • Maintain reasonable administrative, technical, and organizational safeguards appropriate to the processing.
  • Notify the Merchant if, in our reasonable opinion, an instruction infringes applicable Data Protection Law.

4. Merchant obligations

The Merchant will provide lawful instructions, obtain any required notices or permissions, use the service consistently with Data Protection Law, and avoid supplying Personal Data not needed for the service. The Merchant is responsible for the lawfulness and accuracy of its Shopify customer data, audience decisions, campaign content, and response to customer rights requests.

5. Security

DirectSnail’s safeguards include encrypted network transport, scoped authentication, tenant isolation, limited collection, access logging, signed webhook verification, fulfillment idempotency, and retention controls. DirectSnail regularly evaluates these measures and may update them without materially reducing overall protection.

6. Subprocessors

The Merchant authorizes DirectSnail to use subprocessors needed to provide the service. DirectSnail remains responsible for their processing under written obligations appropriate to the services they perform.

ProviderPurposePrimary processing
LobAddress verification, printing, mailing, delivery eventsUnited States
RailwayApplication and database infrastructureUnited States
CloudflareArtwork and application-asset storage through R2United States / global network

Shopify provides the commerce platform, merchant authentication, source data, and billing under its separate relationship with the Merchant. DirectSnail will provide reasonable notice before adding a new subprocessor that materially processes customer Personal Data and will consider reasonable, substantiated objections.

7. Individual rights and assistance

Taking into account the nature of processing, DirectSnail will reasonably assist the Merchant with access, correction, deletion, restriction, objection, portability, and opt-out requests. If DirectSnail receives a request relating to Merchant-controlled Personal Data, we may direct the person to the Merchant and notify or assist the Merchant unless prohibited by law.

8. Security incidents

DirectSnail will notify the Merchant without undue delay after confirming a breach of security affecting Merchant Personal Data. The notice will include available information reasonably needed to understand the nature, likely consequences, affected data, and remediation. Notification is not an admission of fault.

9. Deletion and return

At the end of the services, DirectSnail will delete or return Merchant Personal Data as required by Data Protection Law and Shopify’s mandatory privacy workflows, except where retention is required by law or needed for limited security, financial, suppression, or backup purposes. Retained data remains protected and isolated from ordinary use.

10. Audits and information

DirectSnail will provide information reasonably necessary to demonstrate compliance with this DPA. Where that information is insufficient, the parties may agree to a proportionate audit subject to confidentiality, security, scope, timing, and cost protections. Audits may not expose another merchant’s data or compromise the service.

11. International transfers

If Data Protection Law requires a transfer mechanism for processing outside the originating jurisdiction, the parties will use the applicable standard contractual clauses or another legally recognized mechanism. DirectSnail will apply any required supplementary measures appropriate to the transfer.

12. Order of precedence and contact

If this DPA conflicts with the Terms of Service on the handling of Personal Data, this DPA controls. All other terms remain in effect. Privacy and data-processing questions can be sent to privacy@directsnail.com.
