Code rules
How codes and kits work.
Pricing and privacy are separate. A purchase can unlock printables, codes, and timelines. It does not give SLOWKEPT access to the full letter.
One code belongs to one thread
A Private Thread Code connects two people to one long-term private letter timeline. It is not a new code for every letter.
Reply Kit adds no new code
Reply Kit is for the recipient side of an existing thread. It must use a Private Thread Code that already exists.
The full letter is not stored
Paid kits unlock printables, codes, and timelines. They do not add online storage for the full letter text.
Memory Book is not sold in V1
Memory Book is a future physical archive idea. V1 only validates whether this need matters before anything is produced.
Not sure which one fits?
Start with the free letter flow. You can understand the letter path first, then decide whether a printable kit or private code is needed.
