Companies that handle data for us
Last updated 2026-07-04
Seidwyn relies on four companies to run. Each of them sees a specific
slice of data for a specific purpose. We have a data-processing
addendum (DPA) with each. The list below is the complete current

before they take effect, by email to subscribers and an updated
date on this page.

Payments
Paid subscriptions are not currently open, so no payment processor
receives your data today. Before payments open, the merchant of
record will be added to this list and the date above updated —
card details will never reach Seidwyn directly in any setup.
Why this list matters
When you use Seidwyn, your data passes through these companies under
our instruction. We are responsible for the data they receive on our
behalf. We do not allow them to use it beyond the purpose listed
above. We chose them because their published policies and contractual
commitments align with our privacy posture — specifically: your
image is not retained, not used for training, and not made
available to anyone outside the inference call.
If you are uncomfortable with any of these processors, do not use
Seidwyn. You can write to privacy@seidwyn.com
with questions.
