I built Sweep in Stockholm, Sweden. It is a one-person project with no investors and no ads. Contact: hello@trysweep.dev
When you connect your inbox, Sweep's scan reads only email metadata — sender names, addresses, subject lines, and dates — never the body of your emails. Sweep also needs permission to move mail to your trash, so it asks for a little more than read-only access. The one time Sweep handles a file from a message is when you choose to preview an attachment, described below.
When you tap to preview an attachment, Sweep retrieves that single file from Gmail through the app and shows it to you in your browser. It is only ever the file you chose, only when you ask. The file is streamed to your screen, held in memory only long enough to display it, and never stored by Sweep — close the preview and it is gone.
Sweep processes inbox information only for your active session. Your review session stays in your browser, while Sweep's app service processes requests temporarily in memory. Sweep processes the Gmail metadata it needs temporarily, in memory, to serve your active session; it does not persist inbox content or attachment files in any Sweep database or storage. The only inbox-related data Sweep keeps is three anonymous counters — a running total of ratings, a count of completed cleanups and a count of first-time connections — which hold nothing from your inbox and nothing that identifies you.
Sweep only moves emails to your Gmail trash when you explicitly choose to. Trashed emails remain recoverable in Gmail for 30 days, after which Gmail removes them automatically. Sweep never permanently deletes anything itself.
Sweep uses one temporary session cookie to keep you logged in during your cleanup session. Your theme preference and review progress are saved in your browser's local storage — they never leave your device. There are no tracking cookies.
Sweep uses privacy-friendly, cookieless analytics (Vercel) to understand how the app is used — anonymously. This includes page visits and a few anonymous usage events, for example that a scan finished or a sender was cleared. These events record only that an action happened — never who you are, never your email address, and never anything inside your inbox. No personal data, no identifying cookies, no ad tracking.
If you ask to join the beta, Sweep collects your email address and which inbox you're interested in (Gmail or iCloud). This is the only personal data Sweep stores, and only because you chose to give it. The legal basis is your consent, given when you tick the box on the join form.
Your email is used solely to invite you to the beta and let you know when your spot opens — never for marketing, never shared, never sold. It is kept in a private Google Sheet (Google Workspace, acting as a data processor) and removed as soon as you're onboarded, or whenever you ask. To be removed at any time, email hello@trysweep.dev.
The optional survey is anonymous. It records your answers — how you'd feel without Sweep, which parts work, which inbox to build next, and any notes you choose to add — with no name, no email, and nothing that identifies you. Responses are kept in a private Google Sheet (Google Workspace) so I can see what to build next.
If you tick the box to feature a comment on Sweep's story, only that comment may be shared, always anonymously. You never have to fill in the survey, and you can close it at any time.
Sweep is free — every user gets the full app. If you enjoy it, you can support the project on Ko-fi. Payments are handled entirely by Ko-fi — Sweep never sees or stores your card details, and supporting does not unlock features or change how Sweep works.
Sweep's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Gmail data is used only to provide the features described on this page — never for advertising, never sold, never used to train models.
Sweep relies on a few trusted providers, acting as data processors: Google (Gmail access and, for the survey and waitlist, Google Workspace / Sheets), Vercel (hosting and cookieless analytics) and Ko-fi (optional support payments, handled entirely on their side). Sweep shares only what each needs to do its job, and never sells your data to anyone.
You can revoke Sweep's access to your Gmail at any time at Google Account Permissions. Revocation takes effect immediately.
You have the right to access, correct, or delete any personal data held about you. Sweep stores nothing from your inbox. The only personal data Sweep may hold is your email address — and only if you joined the waitlist. You can have it deleted at any time by emailing hello@trysweep.dev. Everything else Sweep keeps (the anonymous counters and anonymous survey answers) is not linked to you, so there is nothing there to identify or remove.
