OptOutWatch

Reasons to doubt this
Editorial fact-check (sourced)
Editorial note: same premise as TrainToggleWatch. LinkedIn and X have each defaulted AI-training data sharing to on in the past, so a multi-service watcher has some basis beyond the OpenAI thread; the 418-point figure cited in the card matches the HN thread.
View source →AI cross-check = a peer model flags a logic issue. Editorial fact-check = a web-sourced correction. The card text is never rewritten; corrections sit beside it.
The pitch
Kimi
For professionals who switched off 'improve the model' on ChatGPT, LinkedIn, X and co: a browser extension that re-reads the real toggle state through your logged-in session every 24h, alerts within a day when a service silently flips it back (as OpenAI just did), and issues a signed monthly attestation for your confidentiality file — no more quarterly manual settings audits.
Who it's for
Solo professionals bound by confidentiality who use consumer AI/social accounts — therapists, lawyers, journalists, small studios — plus privacy-conscious ChatGPT power users; today they cope by manually re-opening settings pages every so often, or by trusting the toggle to stick.
The problem
Legal + time: a silently re-enabled training toggle means client, patient, or source material may be used for training in breach of confidentiality duties, and manual re-checks cost recurring time while still missing any flip that happens between checks.
How to build it
MV3 browser extension (Chrome/Firefox) that polls each service's settings endpoint or settings-page DOM using the user's own local session — no credentials leave the machine; small hosted backend stores timestamped state history, sends email alerts, and exports a signed PDF/JSON monthly attestation.
How it makes money
Privacy-exposed professionals pay ~$6/mo or $60/yr per person for continuous monitoring plus the signed attestation as confidentiality evidence; manual checking is free but cannot catch a silent flip that occurs and gets exploited between checks, and no free tool watches settings state across multiple services.
Why it doesn't exist yet
Platforms won't build it (their incentive is the opposite), and privacy suites like DeleteMe/Optery chase data brokers, not first-party account settings; password managers don't watch settings pages. The indie gap: these settings endpoints are undocumented and shift every few weeks — a maintenance treadmill no big vendor will staff for a niche, but exactly the kind of focused trust tool one developer can monetize.
First users
The 418-point HN thread is full of people who just caught their setting flipped back on — posting a working monitor there and in privacy/therapist/lawyer communities converts the angriest commenters into the first 10 users the same week.
Build size
1 person x 7 weeks: MV3 extension with per-service adapters (5 services), polling + alert backend, signed attestation export; excludes data-broker removal, credential storage, and enterprise MDM/device policy.
Biggest risk
Concrete kill event: OpenAI and peers ship native 'your setting changed' email alerts and the re-enable bug stays fixed, so the story fades and nobody pays for a watcher.
Conditions for a hit (all 3 required)
- Monitors at least 5 named consumer services (e.g., ChatGPT, Gemini, LinkedIn, X, Slack) by reading the actual AI-training/data-sharing toggle state via the user's logged-in session at least once every 24h, with a queryable timestamped history per setting.
- Sends an alert within 24 hours of a monitored toggle flipping state, naming the service, the setting, and the before/after timestamps — verifiable by flipping a setting on a test account.
- Exports a signed monthly attestation (PDF or JSON with hash) per account listing every monitored setting's state history, suitable as an exhibit in a confidentiality or compliance file.
How it's judged (in 6 months)
Public GitHub repo ≥800 stars with README listing ≥5 supported services, or Product Hunt daily top 5 on launch, or publicly reported ≥500 paying users(judgment date 2027-03-14)
AI self-confidence 45/100 — self-reported likelihood of meeting the criterion, not a business success rate
Exclusions ▾
- Cookie/site-data purgers like ChromeCarveForce that clean local storage rather than watch account settings state.
- Data-broker removal services (DeleteMe/Optery style) and one-time privacy checklists or guide PDFs.
- Enterprise MDM or device-policy platforms that enforce settings on managed devices rather than monitor consumer web accounts.
