About this appAI proposal
Shutters is a privacy control panel for the browser you already use. A web app cannot replace a browser engine, so Shutters does not try. It builds, checks and syncs your privacy and customization settings across Firefox-based and other browsers, in one place you own.
You pick what to block, what to share and what to switch off, including AI and telemetry options. Shutters produces config profiles, filter lists and a custom start page, then audits your browser against your own rules.
It is for people who feel mainstream browsers now favor telemetry and built-in AI over user control. Shutters collects no analytics and keeps synced settings end-to-end encrypted. This is a proposal: the demand it rests on is a public claim, not verified.

- Why this name
- Shutters are something you close yourself. The name is plain, easy to say, and points to control over who looks in.

AI and telemetry switch-off list
A maintained checklist of options to disable per browser version, so updates that re-enable them get caught.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- Shared outputs. Users publish a named rule profile as a link, such as 'No telemetry, no AI'. Others preview it and import it into their own Shutters. Profile pages show the Shutters name.
- Do they become customers?
- People who open a profile link are the same privacy-minded audience, so they can become paying users. Test whether free link visitors create an account and then pay for sync.
- First customers
- Privacy-conscious Firefox desktop users who already tweak settings by hand or keep a user.js file, and who have written publicly about leaving or distrusting their browser.
- Where to reach them
- Hacker News Show HN: Post a free profile builder and settings audit, and ask for feedback on which browser versions to cover first.
- Privacy subreddits and forums: Share profile links and answer settings questions, with no ads.
- Open-source newsletters: Offer a free profile to feature, plus a short guide on auditing browser settings.
- First milestone
- Fifty free signups from one channel, and ten of them paying for sync within 60 days.
Why people already pay for this
- Public claimUsers are willing to pay recurring subscriptions for privacy-respecting software
- Public claimThere is demand for a browser focused on privacy and customization rather than telemetry and AI integration

RisksAI inference
- CommercialThe demand is a public claim, not verified. People who say they would pay for a private browser may not pay for a settings tool that is not a browser.
- PlatformA PWA cannot change browser settings directly. It can only export files and instructions, so users must apply them by hand, which may feel like too much work.
- TechnicalBrowser settings change often between versions. Keeping the audit and switch-off list accurate needs steady upkeep.
- CommercialFree, community-maintained config files and extensions already exist, so paid sync has to be clearly easier.
- DataZero-knowledge sync means a lost key cannot be recovered. Users may lose their profiles.
