QuietCheck: Privacy Scanner — Terms of Service

ℹ️ Note on legal review. These Terms are published by QuietField LLC (Florida); assignment of the app and its intellectual property to the company is pending. They have not yet been reviewed by a licensed attorney. They are grounded in what the app actually does and are written to be relied on, but they should be reviewed by counsel licensed in the governing jurisdiction (Florida, see Section 15) before they are treated as fully settled legal text. Nothing here is legal advice.

1. Acceptance of these Terms

By downloading, installing, or using QuietCheck: Privacy Scanner ("QuietCheck" or the "App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the App. These Terms apply alongside QuietCheck's Privacy Policy, and, because QuietCheck is distributed through Apple's App Store, alongside Apple's own Licensed Application End User License Agreement and App Store Terms of Service, which also govern your use of the App as a matter of Apple's own policy.

2. Description of the Service

QuietCheck is a privacy-protection tool for the person carrying the phone it runs on, not a targeting, tracking, or surveillance tool aimed at other people. Specifically, the App:

Passively scans Bluetooth Low Energy ("BLE") advertising frames for manufacturer identifiers and name patterns associated with known smart-glasses makers (e.g. Meta Ray-Ban, Snap Spectacles), Bluetooth trackers (e.g. Tile, Chipolo), and drones broadcasting a standardized Remote ID signal over BLE, and alerts you when one is probably nearby, with a confidence tier (unverified / low / medium / high) attached to every alert.
Offers an opt-in, heuristic "Hidden Camera Check" that uses your device's camera and flashlight, analyzed live and on-device, to look for a "lens glint" reflection pattern consistent with a camera lens.
Maintains an on-device history of past detections, an optional proximity radar view, an optional approximate-location tag per detection (off by default), an optional shared, anonymous community sighting map, an optional anonymous feedback mechanism for confirming or flagging a detection, a bundled state-by-state recording-consent reference lookup, a CSV export of your history, and companion Apple Watch and Live Activity/widget surfaces.
Every detection mechanism in the App is proximity-only by construction: it can only ever detect what is physically near the device it is running on, at the moment it is running, and has no capability to look up, locate, or monitor a specific device, or person, anywhere else.

QuietCheck is not affiliated with, endorsed by, or sponsored by Meta, Snap Inc., Tile Inc., Chipolo d.o.o., Samsung, TCL, RayNeo, Luxottica, or any other manufacturer referenced in the App's signature database or copy. Any company or product name referenced by the App is used descriptively, to identify whose hardware a detected Bluetooth signal or advertised name belongs to.

3. Eligibility and account status

QuietCheck has no user accounts, sign-in, or registration of any kind — there is nothing to register for and nothing to delete an "account" from. Some optional features (anonymous feedback, the community sighting map) use Firebase Anonymous Authentication behind the scenes purely to satisfy a server-side write-gating rule; this is not a user account and creates no profile, as described in QuietCheck's Privacy Policy. You must be legally capable of entering into a binding contract in your jurisdiction to use the App; if you are using the App on behalf of a minor, you are responsible for that use.

4. Your responsibilities and acceptable use

You agree to use QuietCheck only for its stated purpose — helping the person carrying the phone notice things nearby that could threaten their own privacy — and not to:

Use the App, or information the App surfaces, to identify, locate, monitor, harass, stalk, or otherwise target a specific person or their property. The App is structurally incapable of doing most of this (see Section 2), but you remain solely responsible for how you act on whatever it tells you.
Rely on the App's detections, distance estimates, or the "Hidden Camera Check" as the sole basis for any accusation, confrontation, legal action, or safety decision. See Section 5.
Rely on the App's bundled state recording-consent information as legal advice, or as a substitute for consulting an attorney about your specific situation. See Section 6.
Attempt to interfere with, jam, block, disrupt, or transmit to any device the App detects. QuietCheck only passively listens to publicly broadcast Bluetooth advertisements and camera-visible light reflections; it does not connect to, pair with, or transmit to any detected device, and you agree not to attempt to make it (or anything else) do so using information from the App.
Use the App's "Please stop recording" assertion-card feature, or any other feature of the App, in a way that violates applicable law in your location.
Reverse-engineer, decompile, or attempt to extract the App's source code except as permitted by applicable law, or use the App in any way that violates Apple's own App Store Terms of Service.

You are solely responsible for complying with all laws applicable to your use of the App, including any laws governing recording consent, Bluetooth/wireless-signal monitoring, or drone-detection equipment in your jurisdiction.

5. Detection accuracy — disclaimer

QuietCheck's detections are heuristic and approximate. They are not a guarantee, and you must not treat them as one. The following limitations apply:

BLE-based detection (smart glasses, trackers, drones) matches an advertised Bluetooth manufacturer identifier and/or name pattern against a bundled or server-synced reference list, and assigns a confidence tier — it does not, and cannot, identify a specific device with certainty. A device sharing a manufacturer identifier with, but not actually being, a piece of smart-glasses hardware is a real possibility the App's own confidence-tier system exists to communicate honestly, not eliminate.
Distance/proximity estimates (the radar view) are derived from Bluetooth signal strength using a standard log-distance path-loss approximation and are explicitly labeled approximate everywhere they appear in the App. Signal strength is inherently noisy — affected by multipath reflection, device orientation, obstructions, and transmit-power variance between devices — and the displayed angle of a detected device on the radar is illustrative/cosmetic only, not a real bearing; BLE does not provide direction-finding.
The Hidden Camera Check is a heuristic aid, not a guarantee. It uses a brightness/reflection ("lens glint") heuristic, not a trained or comprehensive detection model, and will miss many real hidden cameras (wrong angle, no reflection at the moment of scanning, bright ambient light, a small or recessed lens) and may flag things that are not cameras at all (jewelry, glass, other reflective surfaces). Do not rely on it as your only way to check a space for hidden cameras.
Background scanning is best-effort only. Apple's Core Bluetooth background execution model does not reliably deliver newly-appearing device discoveries once the App is backgrounded for the kind of broad, unrestricted scan QuietCheck performs. QuietCheck does not claim otherwise, and you should not assume a lack of alert means nothing is nearby.

To the fullest extent permitted by applicable law, QuietCheck disclaims any warranty, express or implied, that any detection, non-detection, distance estimate, or hidden-camera flag (or lack thereof) is accurate, complete, or reliable. Do not use the App as a substitute for your own judgment, situational awareness, or, where warranted, consultation with law enforcement or security professionals.

5A. Safety, emergency services, and assumption of risk — read this

QUIETCHECK IS NOT AN EMERGENCY SERVICE AND IS NOT A SUBSTITUTE FOR CALLING 911 (OR YOUR LOCAL EMERGENCY NUMBER), LAW ENFORCEMENT, OR A PROFESSIONAL SECURITY SWEEP. If you believe you are in danger or that a crime is being or has been committed, contact emergency services and appropriate professionals directly. Do not rely on this App as your means of summoning help.

You acknowledge and agree that:

A detected signal is a clue, not proof. Every alert QuietCheck raises is a heuristic, probabilistic indication — communicated with a confidence tier for exactly this reason — that something matching a known pattern may be nearby. It is not confirmation that any particular device, camera, tracker, or person is present, watching, recording, or acting unlawfully.
There is no guarantee of detection. QuietCheck can miss real devices and can flag things that are not what they appear to be. The absence of an alert does not mean nothing is nearby, and the presence of an alert does not mean a threat exists. Background scanning is best-effort only and constrained by the operating system.
The App does not, and cannot, keep you safe by itself. It surfaces information for the person carrying the phone; acting on that information — including any decision to confront, accuse, flee, record, or contact authorities — is solely your responsibility, and you assume all risk arising from those decisions.
Any current or future personal-safety, "get help," check-in, or covert-alert feature is best-effort and non-guaranteed. Where such a feature relies on the operating system, network connectivity, or your own action (for example, tapping "Send" on a pre-filled message), it may be delayed, incomplete, or fail entirely, and QuietCheck cannot send a message or summon help on your behalf without the platform and your device cooperating. Never rely on any such feature as your only way to call for help.

ASSUMPTION OF RISK. You use QuietCheck, its detection features, and any safety-related feature entirely at your own risk, on an "AS IS" and "AS AVAILABLE" basis (see Section 10), and you assume all risk of harm, loss, or injury arising from your use of, reliance on, or inability to use the App or any of its outputs, to the fullest extent permitted by applicable law.

6. State recording-consent information — not legal advice

QuietCheck bundles a state-by-state reference summary of U.S. recording-consent law, sourced from the Reporters Committee for Freedom of the Press's Reporter's Recording Guide, and surfaces it on a per-detection basis (using either a reverse-geocoded or a manually-set state) and via the "Please stop recording" assertion card.

This information is for general awareness only. It is not legal advice, and QuietCheck is not a law firm. Real recording-consent law has genuine nuance and exceptions — in-person versus phone versus electronic recording, public versus private places, participant versus non-participant recording, and ongoing litigation — that a short, per-state summary cannot fully capture. Several states' classifications are contested or mixed for exactly this reason, and are labeled as such in the App rather than forced into a clean one-party/all-party answer. You must not rely on this feature as legal advice, and should consult a lawyer licensed in the relevant jurisdiction for guidance specific to your situation before taking any action based on it. QuietCheck disclaims all liability for any action taken, or not taken, in reliance on this information.

7. In-app purchases

QuietCheck offers an optional one-time paid upgrade ("QuietCheck Pro") purchased through Apple's In-App Purchase system (StoreKit). As the App actually ships:

Free trial: for the first 24 hours after first launch, QuietCheck gives you full access to every feature — unlimited scans, background scanning, the Unwanted Tracker Alert, the weekly privacy report, the community sighting map, and the Apple Watch companion — with no sign-up, no payment information, and no metering of any kind.
After the trial: the trial-gated features lock, but nothing already recorded during the trial is deleted or hidden — your existing detection history remains fully visible. Continuing to use those features requires a one-time purchase of QuietCheck Pro.
QuietCheck Pro is a single, one-time, non-consumable purchase — there is no subscription and nothing that auto-renews. For a limited window right after your trial ends, Pro is offered at a lower introductory price (com.mbd.quietcheck.pro.lifetime.discount) before returning to its standard price (com.mbd.quietcheck.pro.lifetime); both are the same one-time unlock, and you are charged once.
What Pro unlocks: the same full feature set the trial provided — unlimited scans, best-effort background scanning (subject to the platform limitations in Section 5 — Pro removes the App's own gate, not Apple's underlying constraints), the Unwanted Tracker Alert, the weekly report, Apple Watch complication data, and calendar-triggered "meeting mode." Because it is a one-time purchase, it is a permanent unlock, not an ongoing service you keep paying for.
Billing and refunds: payment is charged to your Apple ID account at confirmation of purchase. QuietCheck has no separate billing system and cannot charge, cancel, or refund a purchase on your behalf; all purchases, refunds, and billing disputes are handled by Apple, per Apple's own Media Services Terms and Conditions.
Restore Purchases: the App provides a "Restore Purchases" control to re-link a previous purchase to a new device or after a reinstall, as required by Apple wherever non-consumable purchases are sold.
No server-side purchase records: QuietCheck determines your Pro status by reading Apple's own on-device purchase and entitlement records directly — it does not send your purchase information to QuietCheck's own Firebase backend or any third party.

8. Intellectual property

The App itself — its code, design, and original content — is the property of its developer (see Section 16 on the developer entity) or its licensors. You are granted a limited, non-exclusive, non-transferable, revocable license to use the App on devices you own or control, solely for its intended personal use, subject to these Terms and Apple's own license terms. All trademarks, product names, and company names referenced within the App's signature database or copy (Meta, Ray-Ban, Snap Inc., Luxottica, TCL, RayNeo, Tile Inc., Chipolo d.o.o., Samsung, and any others) belong to their respective owners and are used descriptively/nominatively only, as detailed in Section 2.

9. Third-party services

QuietCheck uses Firebase (Firestore and Firebase Anonymous Authentication, both Google Cloud services) for three narrow, disclosed, opt-in-or-anonymous purposes: syncing the signature reference database, submitting anonymous detection feedback, and contributing to the anonymous community sighting map. Your use of these features is also subject to Google's/Firebase's own terms and privacy practices for the underlying infrastructure. QuietCheck uses no analytics SDK, no advertising SDK, and no other third-party SDK. See QuietCheck's Privacy Policy for the complete accounting of what each of these three features sends.

10. Disclaimer of warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY THAT THE APP'S DETECTIONS, DISTANCE ESTIMATES, HIDDEN-CAMERA-CHECK RESULTS, OR CONSENT-LAW INFORMATION ARE ACCURATE, COMPLETE, CURRENT, OR RELIABLE, to the fullest extent permitted by applicable law. This disclaimer will be reviewed by counsel for enforceability, including in jurisdictions where certain warranties cannot be disclaimed as a matter of consumer-protection law.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL QUIETFIELD, LLC (THE DEVELOPER OF QUIETCHECK) BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF SAFETY, PRIVACY, DATA, OR PROPERTY, ARISING FROM OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE APP — INCLUDING ANY RELIANCE ON A DETECTION, NON-DETECTION, DISTANCE ESTIMATE, HIDDEN-CAMERA-CHECK RESULT, OR CONSENT-LAW INFORMATION THE APP PROVIDES.

CAP ON LIABILITY. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL, AGGREGATE LIABILITY OF QUIETFIELD, LLC TO YOU FOR ANY AND ALL CLAIMS ARISING FROM OR RELATED TO THE APP OR THESE TERMS, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, SHALL NOT EXCEED THE GREATER OF (a) THE TOTAL AMOUNT YOU ACTUALLY PAID FOR QUIETCHECK PRO IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (b) TWENTY U.S. DOLLARS (US $20.00). Because QuietCheck Pro is a one-time purchase and there is no subscription, for most users the amount paid is a single Pro purchase price or, if the App was used only on the free tier, zero.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some or all of the exclusions and limitations in Sections 10 and 11 may not apply to you; in that case, the liability of QuietField LLC is limited to the smallest amount permitted by applicable law. Nothing in these Terms excludes or limits liability that cannot be excluded or limited as a matter of law.

12. Indemnification

You agree to indemnify and hold harmless the developer of QuietCheck from any claim, demand, or damages arising out of your misuse of the App, including any use that violates Section 4 (Acceptable Use) or applicable law. This provision is subject to attorney review, as indemnification clauses are highly jurisdiction- and context-dependent.

13. Termination

You may stop using the App at any time by deleting it. The developer may suspend or discontinue any part of the App's optional networked features (signature sync, feedback submission, the community heatmap) at any time — the App is designed to degrade gracefully to fully offline, free-tier operation if these are unavailable, so termination of these specific features does not mean termination of the App's core functionality. Sections that by their nature should survive termination (Sections 5, 5A, 6, 8, 10, 11, 12) survive.

14. Changes to these Terms

The developer may update these Terms from time to time, for example as new features ship. Continued use of the App after an update constitutes acceptance of the revised Terms. Material changes will be flagged to users in a reasonably prominent way (for example, an in-app notice); the specific mechanism has not yet been finalized and will be determined with counsel's input before shipping.

15. Governing law and jurisdiction

These Terms, and any dispute arising out of or relating to these Terms or the App, are governed by the laws of the State of Florida, without regard to its conflict-of-laws rules, and (subject to Apple's own terms and to any mandatory consumer-protection law of your place of residence that applies regardless of this choice) you and QuietField LLC submit to the jurisdiction of the state and federal courts located in Florida for any dispute not otherwise subject to an agreed alternative dispute-resolution mechanism.

Note: the inclusion of an arbitration clause and/or a class-action waiver — which are common in consumer-app terms and are recommended for consideration — has been left out of this version pending review by licensed counsel, because their enforceability is jurisdiction-specific. This governing-law and venue selection should be confirmed by counsel licensed in Florida before these Terms are treated as fully settled.

16. The developer / entity

The developer of QuietCheck is QuietField LLC, a limited liability company organized under the laws of the State of Florida; assignment of the app and its intellectual property to the company is pending. Every reference to "the developer" throughout this document means QuietField LLC.

Note on outstanding items: QuietField LLC is formed in the State of Florida. These Terms have not yet been reviewed by a licensed attorney. This document — and in particular the governing-law selection in Section 15 and the limitation-of-liability cap in Section 11 — should be reviewed by counsel, and the intellectual property formally assigned into the company, before these Terms are relied upon as fully settled legal text. Data-protection and privacy questions can be directed to the contact listed in QuietCheck's Privacy Policy.

17. Miscellaneous

If any provision of these Terms is found unenforceable, the remaining provisions remain in effect. These Terms, together with QuietCheck's Privacy Policy and Apple's own App Store Terms, constitute the entire agreement between you and the developer regarding use of the App.

18. Apple-specific terms

Because QuietCheck is distributed through Apple's App Store, the following apply as Apple's required minimum terms for apps using a custom End User License Agreement (rather than Apple's Standard EULA). Exact wording will be confirmed against Apple's current Developer Program License Agreement and App Store Review Guidelines before shipping:

These Terms are between you and the developer of QuietCheck only, not Apple, and Apple has no responsibility for the App or its content.
The license granted to you is limited to a non-transferable license to use the App on an Apple-branded device that you own or control, per Apple's Usage Rules.
Apple has no obligation to furnish any maintenance or support services for the App.
In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you; to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App.
Apple is not responsible for addressing any claims by you or a third party relating to the App, including product-liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer protection or similar legislation.
Apple is not responsible for the investigation, defense, settlement, or discharge of any third-party claim that the App infringes intellectual property rights.
You represent that you are not located in a country subject to a U.S. Government embargo, or on any U.S. Government list of prohibited or restricted parties.
Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and, upon your acceptance, Apple has the right to enforce these Terms against you as a third-party beneficiary.
