1. Acceptance and eligibility
These Terms of Use (“Terms”) are a binding agreement between you and F1v3 Group LLC (“we,” “us,” or “our”) covering the dB Meter app, this website, the optional account service, support and related services (together, the “Service”). By installing the app, buying a subscription, creating an account, or otherwise using the Service, you agree to these Terms and acknowledge the Privacy Policy. If you do not agree, do not use the Service.
You must be at least 13 years old. If you are under the age of majority where you live, a parent or guardian must permit your use and agree to these Terms for you.
2. What dB Meter provides
dB Meter uses your phone's microphone to estimate sound levels in real time, shows session statistics and a frequency spectrum, lets you save readings with notes, and exports PDF reports. If you create an account, it also backs up your readings and makes them available on your other devices.
3. Accuracy and intended use
dB Meter is not a calibrated or certified sound-level meter. Phone microphones differ from one another, have limited range, and are affected by cases, hands, wind and the phone's own processing. The app reduces some of that processing and lets you enter a calibration offset, but the readings remain estimates.
Do not use dB Meter as the basis for legal disputes, noise complaints that require certified measurements, workplace or occupational-safety compliance, building or environmental regulation, hearing-protection decisions, or any medical purpose. The level descriptions in the app (for example “harmful after 8 hours”) are general public-health guidance, not advice about your situation. Where a measurement matters, use a certified instrument operated by a qualified person.
4. Your content
“Your Content” means the readings, labels, notes and reports you create with the Service. You keep your rights in Your Content. If you create an account, you authorise us to store, copy, sync and delete Your Content only as needed to provide and protect the Service. You are responsible for having the right to record and keep the information you enter, including anything about other people.
5. Licence and ownership
We grant you a personal, limited, revocable, non-exclusive, non-transferable licence to install and use the app on devices you own or control. dB Meter, including its software, design and trademarks, belongs to F1v3 Group LLC or its licensors. You may not copy, sell, modify, reverse engineer, or build a competing service from it, except where the law expressly allows.
6. Acceptable use
You may not use the Service to break the law or violate anyone's rights, to access another person's account, to interfere with, overload or bypass the security of the Service, or to resell the Service without our written permission. We may suspend or end access when reasonably needed to protect the Service, its users, or others.
7. Free trial, subscription and billing
dB Meter requires a subscription. When you subscribe for the first time you receive a free trial, currently 3 days, after which the store charges the price shown before you confirmed. The store, not us, decides whether you are eligible for the trial; it is normally available once per Apple ID or Google account.
Subscriptions are sold by Apple (App Store) or Google (Google Play), are billed monthly or yearly as you chose, and renew automatically until you cancel. Cancel in the store you subscribed through at least 24 hours before the renewal date. Cancelling keeps access until the end of the paid period. Deleting the app or deleting your account does not cancel a subscription. Refunds follow the store's rules and applicable law. Prices may differ by country and may change for future billing periods with the notice the law and the stores require.
A subscription is tied to the store account that bought it and to your installation. Restore Purchases brings it back on a new device on the same platform. Moving a subscription between an iPhone and an Android phone requires a dB Meter account, so that the subscription can follow the account.
8. The optional account
You may create an account to back up and sync your readings. You are responsible for activity on your account and devices, except where caused by our breach of these Terms. Use a strong password you do not use elsewhere, keep it private, keep your devices locked and updated, and tell us promptly at support@stax-apps.com if you suspect someone else has used your account. We will never ask for your password.
You can delete your account at any time in the app or as described on the Delete account page. Deleting an account removes your backed-up readings from our servers; readings on a phone stay on that phone.
9. Changes and availability
We may update, change or discontinue parts of the Service. We do not promise it will always be available, error-free, or compatible with every device. Keep your own copies of anything you cannot afford to lose, for example by exporting PDF reports.
10. App stores
If you downloaded the app from Apple or Google, these Terms are between you and F1v3 Group LLC, not the store. F1v3 Group LLC, not the store, is responsible for the app. The store and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
11. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT ANY MEASUREMENT IS ACCURATE, COMPLETE OR SUITABLE FOR ANY PURPOSE.
12. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, F1v3 GROUP LLC WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING HEARING DAMAGE, FINES, DISPUTES, LOST PROFITS OR LOST DATA, ARISING FROM YOUR USE OF OR RELIANCE ON THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM, OR US $50.
These limits do not apply where the law does not allow them.
13. Indemnity
To the extent permitted by law, you will defend and indemnify F1v3 Group LLC against third-party claims arising from your unlawful use of the Service, Your Content, or your material breach of these Terms, except to the extent caused by our own breach or misconduct.
14. Disputes and governing law
Before filing a claim, each side agrees to describe the dispute in writing to the other and try in good faith to resolve it for 30 days. Send notices to support@stax-apps.com.
These Terms are governed by the laws of the State of California. Disputes not resolved informally will be brought in a state or federal court in California. If you are a consumer, this does not take away protections you have under the law where you live.
15. Changes to these Terms
We may update these Terms as the Service or the law changes. We will post the new version here and update the date above. Material changes will be announced in the app before they take effect. Continuing to use the Service after that means you accept the new Terms.
