Privacy policy

Depending on the feature, this can include names, postal addresses, email addresses, account details, message content, uploaded files, order and payment references, and basic technical information.

If you use Mailbook or the API tools, it can also include saved contacts, address requests, preferences, share links, and related activity or security records.

PieterPost is a technical service for creating, printing, stamping, and sending mail. The user who creates a letter or postcard chooses the content, recipient, and address.

The sender is responsible for the content of the letter or postcard, the use of names, addresses, images, files, and other data, and compliance with applicable laws and regulations.

PieterPost is not the author, editor, or substantive sender of mail created by users. PieterPost does not endorse user mail content and does not routinely review content in advance.

A letter or postcard can be sent without sender details on the mail item. This means the recipient cannot automatically see who sent the mail.

PieterPost does not provide a sender's personal data, order data, account data, payment data, IP addresses, or other identifying data to a recipient based on a request, complaint, email, phone call, or support message.

PieterPost does not conduct sender investigations at the request of recipients and does not mediate between recipient and sender.

We use information mainly to run the service: create mail, process checkout, print and deliver items, send transactional emails, manage accounts, power Mailbook and API features, and answer support requests.

We also use limited technical data to keep the service secure, prevent abuse, diagnose problems, and understand overall usage.

PieterPost relies on specialist service providers for things like hosting, database, authentication, payments, email delivery, address lookup, analytics, and print or postal fulfillment.

When a feature is meant to be shared, printed, mailed, or delivered, the relevant information may need to move through those systems so the feature can work. Payment details are generally handled through payment partners rather than entered directly into PieterPost's own systems.

PieterPost only shares data with third parties when needed to perform the service, process data through our service providers, comply with legal obligations, or respond to a valid legal demand, order, or obligation from a competent authority.

When there is a valid demand or order, we provide only the data legally required, to the extent that data is still available within our normal retention periods.

PieterPost processes and stores as little personal data as possible. We keep data only as long as needed to perform the service, handle payment, keep administration, run the technical service, maintain security, provide support, and meet legal obligations.

Content, uploads, print files, delivery information, and technical data may be temporary and automatically deleted. As a result, PieterPost may later no longer have content, sender information, or technical data available.

Complaints or reports from recipients do not automatically lead to additional investigation, identification of the sender, or extended data retention. Only when legally required, for example by a valid demand or order from a competent authority, do we process or share data outside our normal workflow.

Please only upload, submit, or share information that you are comfortable using with PieterPost and that you have the right to share.

If you want to ask about access, correction, or deletion, contact us and we will review the request in the context of the feature and the records involved.
