Privacy policy
This is a static page with no backend, no accounts, and no analytics. That makes for a short privacy policy, and one you can verify rather than take on faith.
In effect since
The short version
We do not collect your personal data, because there is nowhere for it to go. Logs Sanitizer is a static website. There is no database, no login, no analytics script, and no cookie. The log you paste is processed inside your own browser and is never transmitted to us or to anyone else.
Your log never leaves your device
Detection and replacement run in your browser, in a Web Worker. Nothing about the content you paste, upload, or drag onto the page is sent anywhere. This is not only a policy commitment: the production page is served with a Content-Security-Policy that includesconnect-src 'none', which instructs your browser to block every network request this page might attempt — fetch, XHR, WebSocket, EventSource, and beacons alike. If the page tried to send your log somewhere, your browser would refuse to carry it.
You do not have to trust that description. Open your developer tools, switch to the network panel, and sanitize a log. The header itself is reproduced on thehome page, rendered from the same definition the server sends.
What is stored on your device
So that your preferences survive a reload, the tool writes to localStorage in your browser. This never leaves your device and we cannot read it. Three keys are used:
- lsz:settings
- Your preset, sensitivity level, replacement style, which detectors are switched off, and any custom rules or allowlist entries you added.
- lsz:salt
- A random value generated in your browser that makes replacements repeatable, so the same email maps to the same stand-in across files.
- lsz:theme
- Whether you chose the light, dark, or system colour theme.
None of these are cookies, so none of them are transmitted with requests. You can erase all of them at any time by clearing site data for this domain in your browser settings, or by using private browsing, in which case they are discarded when you close the window. Deleting them costs you nothing but your saved preferences — and, if you delete the salt, the ability to produce replacements matching logs you cleaned earlier.
No third-party content
The page loads no third-party scripts, no tag managers, no embedded videos, and no analytics. Fonts are served from this domain rather than a font CDN, so no outside party is told that you visited. There is nothing here that profiles you, and no advertising identifiers are created or read.
Hosting and server logs
Delivering any website requires a connection, and our hosting provider processes the technical metadata that connection produces — your IP address, the time of the request, the file requested, and your user agent string — in order to serve the page and to protect the service from abuse. This is ordinary infrastructure logging that we do not use to build a profile of you, do not combine with anything else, and cannot connect to the contents of any log you sanitize, because that content is never sent. The site is served with Referrer-Policy: no-referrer, so following a link away from here does not disclose where you came from.
If you email us
Writing to us means we hold your message and your email address for as long as it takes to deal with the matter, plus whatever remains in ordinary mail archives. Please do not send us a raw log. If you need to show us data to explain a problem, sanitize it here first — thecontact page explains what to send.
Your rights over your data
Rights of access, correction, erasure, portability, and objection under regimes such as the GDPR, the CCPA, and India's Digital Personal Data Protection Act all attach to personal data held by an operator. We hold none from your use of the tool, so in practice there is nothing for us to disclose, correct, export, or delete — with two exceptions. The first is anything you chose to send us by email, which we will delete on request. The second is the data stored locally on your device, which is entirely under your control and can be erased without asking us. We do not sell or share personal information, because we do not have any to sell or share.
Children
This is a developer tool with no accounts and no data collection, and it is not directed at children. We do not knowingly collect information about anyone, of any age.
Changes to this policy
If this policy changes in substance, the effective date at the top of this page changes with it. Because the privacy properties of this tool are enforced by the response header rather than by promises, the more meaningful thing to watch is the policy the site actually serves.
