Terms

Informational publication

Mark Signals sells fixed informational publications derived from identified public sources. Products are market research only. They are not medical, regulatory, legal, safety, investment, procurement, or manufacturing advice.

Source limits

Public sources may be incomplete, delayed, changed, or corrected. A published record does not establish quality, safety, commercial availability, manufacturing need, buying intent, or future performance. Readers must verify material facts through the linked primary source.

Access and use

A purchase grants the buyer a non-exclusive, non-transferable right to use the delivered publication for the buyer's own business research. Republishing, reselling, sharing paid access, or presenting the publication as professional advice is not permitted.

Memberships

Memberships renew at the disclosed billing interval until canceled. Customers may cancel future renewals through Gumroad. The product page controls the price, cadence, included files, and current coverage.

Support

Reply to the Gumroad receipt for delivery help, corrections, cancellations, or refund requests. Do not send confidential information or card details.
