Tinnitus masking app privacy: which sound apps collect your data?
Learn how to read an App Store privacy label before downloading any tinnitus masking app, then see why siasola discloses no personal data collected at all.
App Store privacy labels tell you exactly what a tinnitus masking app collects before you download it: check identifiers, usage data, diagnostics, and third-party advertising. Practices vary widely, some apps disclose collecting device identifiers and usage data, others disclose nothing. siasola Tinnitus Masking Sounds discloses no personal data collected, no ads, no trackers, and mixes that stay on your device.
What is an App Store privacy label, and why does it matter here?
Apple requires every developer to fill in an "App Privacy" section before an app can go live on the App Store, sometimes described as a privacy nutrition label. It groups what an app collects into three buckets: data used to track you across other apps and websites, data linked to your identity, and data collected but not linked to you. The developer fills this in, Apple does not independently audit every line, so it is a disclosure, not a certification.
Google Play has a parallel system called the Data safety section, listed on every app's store page under a similar set of categories. Between the two, you can compare an iPhone app and an Android app on roughly the same terms without reading either company's full privacy policy line by line.
For a sound masking app built around tinnitus, this matters more than it would for, say, a calculator app. These apps often ask what pitch you hear, when you use the app, and how long you listen, which makes the label worth a genuine look rather than a glance.
How do I read the label before I download?
The five categories worth checking are consistent across most sleep, sound, and audio apps. Use this as a checklist the next time you are comparing options.
| Category | What it means | What to look for |
|---|---|---|
| Identifiers | A device ID, advertising ID, or account ID assigned to you | Whether the developer marks these as linked to your identity or not |
| Usage data | Which screens, sounds, or features you open, and how often | Whether it stays inside the app or is shared for advertising purposes |
| Diagnostics | Crash logs and performance data | Usually lower risk, but check whether it is tied to an identifier |
| Data linked to you | Any category above connected to your name, email, or device in an identifiable way | The bucket to watch most closely, since it can be combined across apps |
| Third-party advertising | Data shared with ad networks or data brokers to track you across other apps | The clearest sign an app's business model runs on targeted ads |
If a label lists nothing under any of these categories, the developer is stating that the app collects no data at all, which is the simplest label to read.
Do popular sleep and sound apps actually collect data?
Practices differ app to app, and by design, since app makers choose their own business models. Many popular sleep and sound apps disclose collecting identifiers and usage data on their current App Store label, often to support account sync, personalization, or advertising. A smaller number of apps in the category disclose collecting nothing at all.
That mix is not surprising given how large this space has become. The white noise app market was estimated at USD 1.21 billion in 2025 and is projected to reach USD 2.86 billion by 2033, according to Verified Market Reports, and roughly 50 million US adults report some form of tinnitus, per CDC survey data, which is a lot of demand for a lot of apps to compete over.
Labels are self-reported and can change between app updates, so treat any comparison, including this one, as a starting point. Open the current listing on the App Store or Google Play before you download, rather than relying on an older screenshot or a review written months ago.
Why does privacy matter more for an app tied to tinnitus?
Most privacy advice applies to any app. Here is the part that is specific to a symptom-adjacent category: the moment a tracker or ad network logs that you installed an app with "tinnitus" in its name, that is itself a piece of information about you, independent of anything you type into the app.
If that identifier gets shared under a third-party advertising category, it can be combined with other signals about you across unrelated apps and websites. You may not mind an ad network knowing you like a certain shoe brand. Knowing you searched for and installed a tinnitus app is a different category of information to hand over, which is one more reason the privacy label deserves a real look, not just the star rating.
What does siasola's own privacy label say?
Plainly: no personal data collected, no ads, no trackers. The 95+ sounds, the pitch exploration tool, and the 5-layer mixer all run from sounds bundled with the app, and mixes you build stay on your device rather than syncing to a server, the same approach covered in our post on sound masking apps that work offline.
siasola is built in Quebec, under Law 25, one of Canada's strictest privacy laws, which shapes the default: collect nothing unless there is a clear, specific reason to. That is a starting design decision, not a policy added afterward, and it is the same reason there is no sign-in needed for the core sounds.

Frequently asked questions
How do I check what an app collects?
Open the app's page on the App Store and scroll to the App Privacy section, which lists categories Apple requires developers to disclose: data used to track you, data linked to you, and data not linked to you. On Google Play, check the Data safety section instead. Labels are self-reported, so check them before each download and after major updates.
Does a free app mean my data pays for it?
Not necessarily, but it is worth checking. Some free apps generate revenue through advertising networks that rely on tracking identifiers, which shows up under the third-party advertising category of the privacy label. Others are free with no ads and no data collection at all. The label, not the price, tells you which model an app actually uses.
What is Quebec's Law 25?
Law 25 is Quebec's private sector privacy law, widely regarded as one of the strictest privacy frameworks in Canada. It governs how organizations collect, use, and disclose personal information, with an emphasis on consent and minimizing what gets collected in the first place. siasola is built in Quebec under Law 25, which shapes its default approach: collect nothing unless there is a clear reason to.
Does siasola require an account?
No personal data collected, no sign-in needed for the core sounds. You can open the app, explore pitches, build a 5-layer mix, and save it, all without creating a profile. siasola's stated policy is no personal data collected, no ads, and no trackers, so there is nothing gathered for an account to attach to in the first place.
