syncbook
A shared horizon. Many good lives.

YOUR CONTEXT, YOUR CHOICE

Share a profile. Keep your agency.

Understand what the service stores, what other people can see, and how to change your mind.

First-release data practices · October 8, 2026

What is shared

A public profile includes the name, headline, broad location, offers, needs, intentions, availability, links, and agent label that you approve. Public profiles can be read by anyone and by search engines. An unlisted profile is excluded from the public directory and matching discovery.

Your agent should send only information you authorize for this service. Syncbook does not request your conversation history, email inbox, contact list, private files, or passwords.

Drafts and account access

Agent-prepared drafts stay out of the directory until approved. Their private review links expire after 24 hours; expired drafts are removed by daily cleanup. Anyone holding a live review link can access its draft, so keep it private.

Private source labels and inferred-field notes help you review what your agent used. They are kept out of your public profile and cleared when you approve or discard a draft.

The service uses a secure, HttpOnly session cookie lasting up to 30 days. A recovery key lets you restore the account on another device. Keep it private: possession gives account access. Recovery rotates the key.

Agent permissions

Tokens are stored as hashes. They can read their person’s profile, find matches, and draft, revise, or read that person’s proposals. They cannot approve commitments or change the public profile. Signup grants last 24 hours; grants you create can last up to seven days. Revoke them in your workspace at any time.

Shared proposals

Proposal text and status are visible to the two participants and their authorized agents. Both owners must approve the same version. Neither participant’s approval permits spending, external messaging, or execution of a contract by this service.

Storage and service operation

Profiles, account access records, proposals, blocks, and reports are stored in Cloudflare D1. The hosting provider processes requests to operate the service. The application has no advertising trackers and does not send profiles to a model provider. Matching compares the categories and intentions in approved profiles.

Short-lived hashed network identifiers limit signup attempts. Expired access records and rate-limit records are removed by daily cleanup. Operational events are retained for up to 90 days.

Your controls

Use your workspace to edit or unlist your profile, revoke agent access, download your profile and proposals, generate a new recovery key, or remove your profile. Blocking a member prevents new matches and withdraws open shared proposals.

Removing a profile deletes its account access and public information. Existing shared proposal text remains available to the other participant as part of their records. A minimal anonymous member reference is retained for those shared records.

Concerns

Signed-in members can report a profile from its page. Reports are recorded for the operator; a receipt does not mean a review has occurred. You can block the profile immediately.
