Blinkr privacy
Last updated 2026-08-28
The short version. Blinkr has no idea what you look at all day, and likes it that way. It reads four tiny signals and keeps a small tally on your Mac. It contacts us for two things only: an optional weekly check for a new version, and — only if you have entered a business license key — a re-check of that key about once a day. This website is a separate matter: buying a business license or subscribing to the newsletter does give us your email address, and that is described below.
What Blinkr reads
Four signals, all local
To time breaks well — and to hold them when a break would be rude — Blinkr reads exactly four things, and none of them says anything about what you are doing:
- How long since you last touched the keyboard or mouse. A timestamp, never which keys — Blinkr cannot see what you type.
- Whether any camera or microphone is in use. The same yes/no flag the menu-bar green dot uses — never any video or audio.
- Whether a window is covering a whole display. Geometry only — never window titles or contents. This is why Blinkr needs no Screen Recording permission.
- Whether the screen is locked.
What stays on your Mac
Blinkr keeps a small daily tally of breaks taken and skipped, plus your settings, in the app's preferences. The tally is kept for 90 days and never leaves the Mac. There are no accounts and no identifiers.
No permissions
Blinkr never asks for a single macOS permission prompt. Not accessibility, not screen recording, not the camera — nothing to grant is the point.
Network connections
There are two, and neither one happens by default on a personal install without your say-so.
The update check
Blinkr checks twoplus11.com's update server about once a week, via Sparkle, to ask whether a newer version has been released. That request sends the app version and macOS version in a standard web request — nothing else. If an update exists, Blinkr downloads it from us and installs it in the background, taking effect the next time you open the app; it verifies the update's cryptographic signature first, and a download that does not verify is refused. Turning the check off in Settings stops all of it — check, download and install — and you can still Check for Updates by hand whenever you like.
The business license check
This one does not happen at all until you enter a business license key. Personal use is free and needs no key, and with no key entered Blinkr never contacts the licensing server — not once, not at launch, not in the background.
Once a key is entered, Blinkr sends it to api.twoplus11.com to check that it is valid, and re-checks about once a day so a cancelled or reassigned seat stops working. That request carries the key, the app version, a name for this computer (which you can edit in the License window), and a machine identifier — your Mac's hardware serial number put through a one-way hash, so the same Mac is recognized as the same seat without the serial itself ever being sent. Nothing about your breaks, your settings, your screen or your habits is included. If the licensing server cannot be reached, your license keeps working offline for three days rather than failing shut. Remove the key in the License window and the calls stop.
Links you click
Clicking Help or Review in the app's footer opens your browser with the app name and version pre-filled, so you don't have to type them. That is your browser making the request, and only when you click.
This website
Everything above is about the app. The pages on twoplus11.com/blinkr/ are a website, and a website you buy from cannot collect nothing.
Buying a business license
The checkout on the Blinkr page asks for your company name, a work email address and the number of devices. We keep those three things because they are the license: the key is emailed to that address, and the record is what evidences the purchase. Payment is handled by Stripe — your card number goes straight to Stripe and we never see or store it. Personal use is free and involves none of this.
The newsletter
If you subscribe, we store your email address, and only to send the occasional note about a new Mac app. You confirm the address first — one email with a link, and you are not subscribed until you click it — and every message carries a one-click unsubscribe that works immediately. The list is never sold, rented or shared.
Downloads and server logs
Each download is counted so we know roughly how many people took the app. The record is the date, the app, your browser's user-agent string, and a salted hash of your IP address — never the address itself, and the salt changes every day, so the same visitor cannot be followed from one day to the next. It is a count, not a profile, and it is tied to no name, account or license. Like any website, the host also keeps standard server access logs for security and operations.
If you email us
We receive your address and whatever you put in the message, and use it only to reply. To ask what we hold about you, or to have it deleted, write to jeremy@twoplus11.com — we answer within 30 days. Deleting a business-license record also ends that license, since the record is the license.
What we never do
- The Blinkr app contains no analytics or tracking of any kind.
- Never records your screen, camera, microphone, or keystrokes.
- No accounts and no sign-in. Blinkr contacts our licensing server only once you have entered a business license key — never for personal use.
- Nothing is ever sold, rented or shared — not your email address, not the license record, not anything the app knows.
- The app itself uses no third-party services. Stripe handles payment on this website, and nothing else does.
Children
Blinkr is a general-purpose tool and is not directed at children under 13, and we do not knowingly collect personal information from children under 13. The app collects nothing from anyone; the only personal information we hold at all is what an adult buyer or subscriber types into this website.
Changes
If this policy ever changes, the updated version will be posted here with a new date, and material changes will be noted in the changelog.
