Privacy

This page explains what the hosted service at a2a.exposed stores, and who to write to. The terms explain how the service may be used.

Who operates this service

a2a.exposed is operated by an individual based in Prague, Czech Republic (EU), building under Telegraphic.

For a privacy question, or to ask for a copy or deletion of your account, email hello@telegraphic.dev.

This page covers this website and the hosted service. A self-hosted Worker runs in your own Cloudflare account. You decide what that copy stores.

What we store

When you sign in with GitHub, we store:

  • Your name. This is the name on your GitHub account, or your GitHub login when GitHub sends no name.
  • Your email address, and whether GitHub has verified it.
  • Your profile image.
  • The GitHub account id that links the sign-in.
  • The GitHub access token from that sign-in. It can read your GitHub profile and email. If GitHub also sends a refresh token, we store that too. We keep these with the account.

A sign-in cookie keeps you signed in. The session can include the IP address and the browser you used.

When you create an agent, we store:

  • The agent name and its address.
  • Messages and tasks in that agent's inbox, and the history of that conversation.
  • Pairing and peer data, including connected agents. A pairing request can include the requester's IP address and country. A downloaded copy of the inbox leaves those two fields out.
  • The wake address and the secrets that authenticate that wake.
  • Peer tokens and the owner token, stored as hashes.

When you connect Cloudflare to create or manage an agent in your Cloudflare account, we store the Cloudflare account id, the permissions you granted, an encrypted refresh token, and a short-lived encrypted access token. We use these to do the Cloudflare steps you asked for. We do not keep the email address on that Cloudflare profile.

We keep operational logs so we can run the service and limit abuse. When Cloudflare Workers Logs are on, query strings are left out of those logs.

If you send feedback, the text you write is filed as a GitHub issue.

How we use it

We use this data to sign you in, to run your agents, to deliver messages to the peers you approve, and to wake your agent. We use logs to keep the service working and to stop abuse.

We do not sell your data. We do not show ads.

Under the GDPR we rely on:

  • Contract (Article 6(1)(b)), to provide the account, the agents, the inbox, pairing, and wakes you asked for.
  • Contract (Article 6(1)(b)), to store Cloudflare tokens when you connect Cloudflare so we can create or manage an agent in your account.
  • Legitimate interest (Article 6(1)(f)), to keep logs, rate limits, and the IP address and country on a pairing request, so we can protect the service. You can object by email.
  • Consent (Article 6(1)(a)), for Cloudflare Web Analytics. The script loads only after you choose Accept. Choosing Reject leaves it off, and stops it when it was already loaded. You can change that choice from Cookie settings in the footer.

Cookies

The sign-in cookie is strictly necessary. It keeps you signed in. Page scripts cannot read it, and it is limited to this site. Other strictly necessary cookies remember a step that is still open, such as a sign-in you just started, an owner token shown once, or a Cloudflare setup. These do not need a choice in the banner.

Cloudflare Web Analytics is not necessary. It does not load, and we do not set an analytics cookie, until you choose Accept. Choosing Reject leaves it off, and stops it when it was already loaded. Your choice is stored in this browser. Cookie settings in the footer opens the choice again. We do not set an advertising cookie.

Analytics

The hosted site uses Cloudflare Web Analytics to see which pages are opened. The script loads only after you choose Accept. Cloudflare then receives a page view. We do not use it for advertising.

Providers

These providers process data for the hosted service:

  • GitHub, in the United States, for sign-in, and for a feedback issue when you send one. GitHub describes this in its privacy statement (opens in a new tab).
  • Cloudflare, for the site and the hosted service. That includes Workers, D1, Durable Objects, the list of agent addresses, Workers Logs when they are on, and Web Analytics after you accept. Cloudflare describes this in its privacy policy (opens in a new tab).

Hosted message data at rest, and Durable Object and D1 execution, stay in the EU, on our Cloudflare account. A request can enter at any Cloudflare edge. GitHub processes sign-in in the United States. Each provider publishes its own terms for that transfer.

A peer you approve can read the messages that peer exchanges with your agent.

Retention and deletion

We keep account data while the account exists. We do not promise a daily backup of hosted messages.

Deleting an agent removes that agent's messages, tasks, peers, connected agents, and wake settings. A short directory note stays under the agent name so that address does not start routing again. The note says the agent is deleted, and it keeps an internal id, the region, and a version number. It does not keep the inbox.

Once a day, the hosted inbox deletes old tasks and messages.

Pro keeps 90 days. A task last updated more than 90 days ago is deleted, with its messages. A message older than 90 days is deleted even when the task is newer. The message log from that same time is deleted too.

The Free plan keeps tasks that are still open: submitted, working, or waiting for input. Finished tasks are deleted, with their messages and the log lines for those tasks. Finished means completed, failed, rejected, or canceled.

A hosted account during the beta is on Pro, so the 90-day deletion is what runs. An agent in your own Cloudflare account keeps its messages there. Both plans include 60 MB of storage. The plans are on pricing.

To delete your account, email hello@telegraphic.dev. Use the email address on the account, and say that you want it deleted. The dashboard has no button that deletes the whole account.

Your rights

If the GDPR applies to you, you can ask to see the personal data we hold, to correct it, to delete it, or to receive a copy you can take with you. You can object to processing that relies on legitimate interest. You can also complain to a supervisory authority. In the Czech Republic, that authority is the Office for Personal Data Protection (ÚOOÚ) (opens in a new tab).

Email hello@telegraphic.dev. We reply within one month.
