When ResponseAI reads a page

On Gmail, Outlook and LinkedIn, ResponseAI reads the open message only when you open its panel. On Fiverr it works only after you turn it on in Settings and Chrome asks for your permission; you can turn it off at any time. On any other website it gets only the text you select and send with the right-click menu. It does not read your inbox in the background, and it never sends messages for you.

What we process

When you ask ResponseAI to write, we send the following to our server (hosted by Cloudflare) and then to the API of Anthropic PBC in the United States, which writes the replies:

• the message text in the panel (the message read from the page, the text you selected, or text you pasted), if you chose to include it;
• what you typed about what you want to say, and any details you added;
• your choices: tone, reply language, situation, and the text of your own template if you used one;
• your style settings: the name, sign-off and style note you entered, your language for the "Means" lines, and the language of the extension's menus;
• the kind of website (for example Gmail or Fiverr), and your current date and time zone, so that times and deadlines can be shown in your time.

We do not store this content on our servers. It is processed to write the replies and then discarded. Anthropic does not use API data to train its models and deletes it after a limited retention period under its own policy.

Messages can contain personal information about other people, such as names or email addresses. Please do not use ResponseAI on messages with sensitive information, such as health or financial details.

Signing in with Google

Signing in with Google is optional: you can use your 3 free replies without it. If you sign in, your free replies and your subscription belong to you as a person and work on every computer you use. Google shows its own sign-in window. ResponseAI asks Google only for basic sign-in (the "openid" and "email" scopes). We never see your Google password, and we do not get access to your Gmail, your contacts, your files or any other Google data.

From Google's answer, our server makes two one-way codes (keyed hashes, which cannot be turned back into the original): one from your Google account number and one from your email address. We store only these codes, never your email address or your Google account number. The account code holds your free replies and subscription. The email code is used only to match a payment made with the same email address to your account. Your browser keeps a signed sign-in code for up to 180 days; signing out in Settings deletes it. If you do not sign in, your free replies and your subscription belong to this installation of the extension.

ResponseAI's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

What stays on your device

These are saved only in your browser's extension storage and are removed when you remove the extension:

• your settings (name, sign-off, style note, languages, text size, reminder options);
• your templates;
• the special days you add (a person's name, the date, the type of day and the language);
• your last replies, kept for 7 days so you can see them again;
• if you signed in with Google, the signed sign-in code described above.

The name and details of a special day are sent only when you ask ResponseAI to write the message for that day, as part of the request described above. Reminders read aloud use your browser's built-in speech on your device. This option is off unless you turn it on.

What we store on our server

• A random identifier created in your browser, used to count your free replies and check your subscription.
• If you signed in with Google: the one-way code of your Google account and the one-way code of your email address, linked to your reply count and subscription status.
• A count of how many replies you have written.
• Your subscription status (active or not).
• If you send feedback (a reason on the "free replies used" screen, or a message through "Send feedback"): what you sent, the time, and the first 8 characters of your random identifier. Please don't include private details in feedback.
• Anonymous monthly totals per country of how many people get their first reply, how often people sign in, how often the "free replies used" screen is reached and how often feedback is sent. The country comes from your internet connection and is not stored with your identifier.

We do not store your name, your email address or the content of your emails and messages on our servers. The extension has no ads and no tracking, and we do not sell any data.

How we protect data

All connections are encrypted (HTTPS). Only the ResponseAI extension and this website can call our server from a browser. Requests are limited in size and speed; your connection's address is used for that only in memory and is never stored. Sign-in codes are signed with a secret key, and the AI service key never leaves our server.

Message check and scam warnings

The mood, deadlines and scam warnings are automatic hints written by the AI. They can be wrong. Always use your own judgment.

Who is responsible

ResponseAI is responsible for the personal data described in this policy. You can reach us at responseaisupport@gmail.com.

Why we may use your data (legal basis)

• To write the replies you ask for and to run your free replies and subscription: this is needed to provide the service you requested.
• To keep the service secure and working: our legitimate interest in preventing misuse.
• Feedback you choose to send: your consent, given when you tap a reason or send a message.
• Anonymous country totals: our legitimate interest in understanding where the service is used and where it feels too expensive.

How long we keep data

• Message content: not kept. It is discarded once the replies are written.
• Usage record (random identifier or account codes, reply count, subscription status) and feedback answers: kept while you use ResponseAI, and deleted when you ask us.
• Data in your browser: kept until you delete it or remove the extension.

International transfers

Our service providers are located outside your country, including in the United States. Your text is transferred to them only to write the replies you asked for. Where the law requires it, these transfers rely on our providers' data protection terms, such as Standard Contractual Clauses.

Payments

Payments are handled by Lemon Squeezy, which acts as the merchant of record. Your card details are entered on their checkout page and never reach our servers. Their privacy policy applies to that part of the process.

Third parties we use

• Anthropic writes the replies.
• Google provides the sign-in.
• Cloudflare hosts our server and stores the usage counter.
• Lemon Squeezy processes subscriptions and payments.

Children

ResponseAI is not meant for children under 16.

Your rights

Depending on where you live, for example under the GDPR in the European Union and the United Kingdom, you can ask us to access, correct or delete your data, to restrict or object to its use, and to receive a copy of it. You can withdraw your consent for feedback at any time. To make a request, write to the address below. Because we do not know your name or email address, we may ask you for details that help us find your record; if you signed in with Google, tell us the email address you used, and we turn it into the same one-way code to find your record. You also have the right to complain to your local data protection authority.

Your choices

You can stop all processing by removing the extension from your browser, which also deletes the data stored in your browser. To ask us to delete the usage record linked to your identifier or account, contact us at the address below.
