Privacy Policy

Last updated: 2026-04-18

TL;DR — DontSleep does NOT collect, transmit, or store any personal information about you. It runs entirely on your own Mac. The only network traffic it can make is (1) fetching a banner ad feed and (2) firing an impression pixel when a banner is shown — both of which you can disable in one click.

1. What DontSleep does on your Mac

DontSleep is a small menu-bar application that prevents your Mac from going to sleep while specific processes (that you choose) are running. To do that it:

Reads the output of /bin/ps -Axo comm= every few seconds to see which processes are running. This list stays on your machine.
Spawns /usr/bin/caffeinate when suppression is active.
Optionally runs sudo -n pmset -a disablesleep 0/1 if you opted into the lid-closed mode. The required sudoers entry is narrowly scoped to just those two commands and is written only after you click "Install…" and enter your admin password.

2. What data DontSleep does NOT collect

No analytics / telemetry.
No crash reports sent to us.
No user accounts, no logins, no cloud sync.
The list of processes you watch is stored locally in ~/Library/Preferences/com.haru.dontsleep.plist and never leaves your computer.

3. Advertising (optional)

When suppression is active, DontSleep can display a small sponsored banner in the bottom-right corner of your main screen.

Ad delivery

Two provider modes are supported:

House Ads — fetches a static JSON file from an HTTPS URL you (or the app's publisher) configured. Only metadata about the creative (headline, image URL, click URL) is returned.
EthicalAds — posts a request to server.ethicalads.io to get the next creative. The request includes only non-identifying fields (publisher id, placement name, keywords). See EthicalAds' own privacy policy.

Impression tracking

When a creative is shown for the first time during an app run, the app issues a single HTTP GET to the creative's impressionUrl (if one is provided). The User-Agent is hardcoded to DontSleep/x.y. No user id, no IP header injection, no cookie handling. If the creative has no impressionUrl, nothing is sent.

Click tracking

Clicks open the creative's click URL in your default browser via NSWorkspace.open. From that point onward, you are interacting with the advertiser's own website under their own privacy policy — DontSleep is not involved.

Turning ads off

Open Preferences… → 広告表示 and toggle the switch off. The banner will never appear again and no network requests for ads will be made.

4. Permissions DontSleep asks for

Admin password (one time) — only if you opt into pmset disablesleep mode. Used to install a narrowly scoped sudoers rule. You can remove the rule later with scripts/uninstall_sudoers.sh.
Network access — only for ad delivery (above), and only when suppression is active and ads are enabled.

5. Children

DontSleep is a developer tool; it is not directed at children under 13 and does not knowingly collect data from children.

6. Changes to this policy

If this policy changes meaningfully, the updated version will be published at this URL and the "Last updated" date at the top will be bumped.
