Privacy policy

KissMail for Mac · Effective 22 October 2026

Summary

KissMail is an email app that runs on your Mac. It has no server and no analytics. The developer never receives, stores or sees your email, your contacts or your Google credentials.

Google user data KissMail accesses

With your permission, KissMail uses the Gmail API scope https://www.googleapis.com/auth/gmail.modify to:

• read your messages, threads, labels and attachments so it can display them;
• send the messages and replies you write in KissMail;
• archive conversations (and undo an archive) and mark messages read or unread, only when you ask;
• read your Gmail address to name the account in the app.

It also uses the read-only Google People API scopes https://www.googleapis.com/auth/contacts.readonly and https://www.googleapis.com/auth/contacts.other.readonly only to suggest recipients' names and addresses while you write a message. KissMail never creates, changes or deletes your contacts.

KissMail never deletes or trashes messages. Drafts you write stay on your Mac.

Where your data is stored

• Your messages are kept in a local cache in KissMail's folder on your Mac (~/Library/Application Support/KissMail or the app's sandbox container), so you can read them offline.
• Contact names and addresses used for suggestions stay on your Mac.
• Your Google refresh token is stored in the macOS Keychain on your Mac.
• Nothing is copied to the developer or to any third-party server. KissMail connects only to Google (accounts.google.com, oauth2.googleapis.com, gmail.googleapis.com, people.googleapis.com).

Sharing

KissMail does not sell, share, or transfer Google user data to anyone. It does not use your data for advertising, and it does not use it to develop, improve or train generalised artificial intelligence or machine learning models. No human reads your data.

Some actions you choose can contact other parties: opening a link opens it in your web browser; the Full HTML reading mode loads the images the sender placed in the message, as most email apps do; Unsubscribe contacts the address the sender gave for unsubscribing.

Limited Use

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

Removing your data

• In KissMail, Settings → Accounts → Remove this account revokes KissMail's access at Google and deletes that account's token, cached mail and KissMail drafts from your Mac. Nothing is deleted in Gmail.
• Revoke KissMail's access at any time at myaccount.google.com/permissions.
• Deleting the app and its folder removes the local cache. The Keychain item org.kissmail.KissMail can be removed in Keychain Access.

Children

KissMail is not directed at children under 13.

Politique de confidentialité (français)

KissMail est une application de courrier qui fonctionne sur votre Mac, sans serveur ni mesure d'audience. Le développeur ne reçoit, ne conserve et ne voit jamais vos courriels, vos contacts ou vos identifiants Google.

Avec votre accord, KissMail utilise l'autorisation Gmail gmail.modify pour afficher vos messages, libellés et pièces jointes, envoyer ce que vous écrivez, et archiver ou marquer lu ou non lu quand vous le demandez. Les brouillons restent sur votre Mac. Il lit aussi vos contacts Google en lecture seule (contacts.readonly et contacts.other.readonly), uniquement pour suggérer des destinataires pendant la rédaction ; il ne modifie jamais vos contacts. Il ne supprime jamais définitivement un message.

Les messages et les contacts suggérés sont conservés sur votre Mac ; le jeton Google est rangé dans le trousseau macOS. KissMail ne se connecte qu'aux serveurs de Google. Il ne vend, ne partage et ne transfère aucune donnée, ne s'en sert pas pour la publicité ni pour entraîner des modèles d'intelligence artificielle. Ouvrir un lien, afficher un message en HTML complet ou se désabonner contacte les adresses choisies par l'expéditeur.

L'utilisation des informations reçues des API Google respecte la Google API Services User Data Policy, y compris les exigences de Limited Use. Dans KissMail, Réglages → Comptes → Retirer ce compte révoque l'accès chez Google et efface le jeton, le cache et les brouillons de ce compte sur votre Mac. Vous pouvez aussi retirer l'accès à tout moment sur myaccount.google.com/permissions. Contact : hello@kissapps.studio.
