Welcome to Freq'n Truth Speaker Tester ("we," "us," "the app"), developed by Qualhalla. We're committed to transparency about data practices in our Android app.
We do not maintain user accounts or collect personal information on our own servers. The app uses third-party SDKs that may collect certain data automatically for ads and analytics:
Purchases are processed entirely by Google Play. We do not receive or store payment details such as credit card numbers. We only receive confirmation of purchase status to unlock premium features.
Data handled by these SDKs is encrypted in transit and processed under Google's policies. We do not combine this data with other datasets to identify you.
This app requests microphone permission to analyze audio frequencies in real-time for speaker testing and frequency response measurements. Audio data is processed entirely on your device and is never recorded, stored, or transmitted to any server. The microphone is used solely to analyze audio frequencies and generate frequency response measurements.
The app stores the following data locally on your device:
This local data is not transmitted to us or any third party.
We do not sell your personal data.
In the European Economic Area, the United Kingdom and Switzerland, advertising and analytics data is used only in line with the consent choices you make in the app. Until you make a choice, the app does not initialise the ad SDK, request ads, or enable analytics collection.
If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows a consent form from Google's User Messaging Platform the first time you open it. No ads are requested and no analytics data is collected until you respond to that form. You can accept, refuse, or use Manage options to choose individual purposes.
You can change or withdraw your choices at any time from inside the app:
This entry point appears wherever consent rules require it. Withdrawing consent stops personalised advertising and closes analytics collection; the app remains fully usable, and you may still see non-personalised ads, which do not rely on your consent to use your data for targeting.
We share data with Google (AdMob, Firebase, Play Billing) and their advertising/analytics partners to provide ads, measurement, and analytics. We do not share data with other third parties for marketing purposes.
Ad SDKs may use cookies or similar technologies to deliver and measure ads. App settings you change are stored locally on your device and are not sent to us.
We do not store personal data on our own servers. Data collected by Google and its partners is retained and processed according to their policies and may be processed on servers outside your country.
This app is not directed to children under 13 and contains advertising. Parents/guardians should supervise use by minors.
Depending on your region, you may have rights to access, delete, or limit processing of your data. Because we don't maintain accounts or store personal data ourselves, requests related to ad/analytics data are generally handled via device controls and Google's mechanisms. If you are in a region where consent is required, you can withdraw it at any time using the Privacy choices option described in section 5, and withdrawing consent does not affect the lawfulness of processing carried out before you withdrew it. You can also contact us and we'll assist where possible.
We may update this policy. We will post the updated version here and change the "Effective date."
