Your mail is your business.
Unpile privacy policy

Our approach
Unpile is made by David Marcantonio to help you organize your inbox in small, enjoyable bursts. We do not receive, store on developer-operated servers, sell, or inspect your inbox or reply content. The app has no advertising, analytics, tracking SDKs, or developer-operated mail service. You do not create an Unpile account.
Access to Apple Mail
With your permission, Unpile reads account and mailbox information, senders, subjects, message text, and message identifiers from Apple Mail on your Mac to display and organize the stack you choose. The app must process this information locally to work; it does not send it to us. Trash, Move, and Reply & Archive change mail through Apple Mail when you choose those actions. Snooze records when a message should return to the app.
What stays on your Mac
Unpile stores settings, mailbox mappings, snooze records, and stack progress locally. Opening a reply creates a saved local draft containing the original message, recipient addresses, subject, reply text, and send-status records. Files you attach are copied into the app’s local storage. These copies support draft recovery and help prevent duplicate sends after interruption. The app does not maintain a separate persistent copy of your whole inbox.
Local retention
Saved drafts, completed reply records, quoted original email text, and attachment copies are currently retained in the app’s local storage without an automatic expiry. Removing an attachment from a draft removes its selection but does not erase its stored copy. There is currently no in-app command to erase all saved data. Removing the application alone may leave its local data behind. Your Mac’s account permissions and device protections apply; Unpile does not add a separate password or promise end-to-end encryption for these files. Device backups may also include local app data under your backup settings.
Optional iCloud Sync
iCloud Sync is off by default. If you enable it, Unpile uses your private CloudKit database to sync batch size, snooze settings and times, mailbox mappings, message identifiers, and remaining-stack progress. Sync records also contain a hashed mail-account identifier, timestamps, and revision identifiers. Message identifiers and mailbox paths can contain personal information; hashing an account identifier does not make all synced metadata anonymous. Email bodies, reply drafts, attachment files, contacts, and mail passwords are excluded from this app sync. Apple operates iCloud. Private CloudKit records are not visible to us through Apple’s developer portal.
Turning sync off and managing data
Turn off iCloud Sync in Unpile settings to stop further app sync work; an already submitted request may finish. Turning sync off does not delete existing local or iCloud data. Uninstalling Unpile does not automatically delete its iCloud records. You can manage app storage through the controls Apple provides for your iCloud account; this version does not include an in-app cloud-erasure command. Keeping sync enabled on another Mac can recreate stored state. Contact support for guidance before removing recovery records, especially if a send is still awaiting confirmation.
Replies and your mail provider
When you send a reply, its text, recipient addresses, and selected attachments go to the recipients through Apple Mail and your configured mail provider. Moving or trashing mail may also update your provider’s servers. Your provider handles your mail account and credentials; Unpile does not ask for or store your mail password. Apple and your mail providers operate under their own privacy policies.
Optional Contacts and file access
Contacts permission is optional. If allowed, Unpile searches contact names and email addresses on your Mac to suggest recipients. It does not upload your address book to us or to its CloudKit database. Addresses you choose become part of your local draft and are sent when you send the reply. You can type addresses without Contacts access. Files are accessed when you choose them in the file picker. Revoke Contacts or Mail Automation access in System Settings → Privacy & Security; doing so does not erase already saved drafts.
Support and system services
If you choose to contact support, the information you send will be received for the purpose of answering your request. Do not include private email content, attachments, or passwords. The app does not automatically send us logs or diagnostics. Apple may process App Store transactions, system diagnostics, and iCloud service information under its own settings and policies; Unpile does not add its own telemetry service.
This website
The website is intended to be hosted on GitHub Pages. GitHub processes technical request information such as IP addresses to deliver and secure hosted pages, under its privacy policy. We do not add visitor analytics, advertising, tracking cookies, or a mailing-list form. The main site hosts its font files itself. Visiting the site does not give it access to your mail or the app’s private iCloud database.
Changes and contact
We will update this policy if the app’s data practices change. For privacy questions, support, or data-management guidance, email hello@unpile.me. Please do not send private email content, attachments, or passwords.
