Privacy Policy
Somnia · Last updated: October 28, 2026
In short: Somnia never asks for your name, email, location, or access to your microphone, contacts or photos. Your mixes and settings are stored on your phone. We use an anonymous identifier to count likes and plays, and Google AdMob shows ads. Searches are only shared if you turn that on. You can delete your data from Settings → Your data.
1. Who is responsible
This policy applies to the Somnia app for Android and its web version (“Somnia”, “we”). The data controller is OTJH LLC, United States. You can write to us at otjhllc@gmail.com with any privacy question.
2. What data we use and why
| Data | Purpose | Legal basis |
|---|---|---|
| Mixes, volumes, favorite sounds, settings, timer | Making the app work. They stay on your device; we never receive them. | — |
| Anonymous user identifier (created automatically, no sign-up) | Saving your likes and favorite songs and avoiding duplicate counts. | Performance of the service |
| Likes, favorite songs and plays (which song and how many seconds) | Showing each song's public totals and ordering content. Totals never identify anyone. | Legitimate interest |
| Searches typed in the catalog, normalized, with a hash of a random device id | Learning which soundscapes are missing and creating new variations. Only if you turn on “Share my searches”; it is off by default. | Consent |
| Mixes you choose to publish and reports about public mixes | Showing them in the public library and moderating them. | Performance of the service |
| Device advertising ID, IP address, device model and OS, ad interactions | Showing ads, measuring them and preventing fraud, through Google AdMob (see section 3). | Consent (EEA, UK and Switzerland) or legitimate interest |
| Local counters of videos watched and what you got with them (extra layer, mix slots, Full Night) | Applying ad limits and granting what you earned. Stored on your device. | — |
We do not collect: name, email, phone number, location, contacts, photos, microphone audio, health data or sleep data. Somnia does not record or analyze your sleep.
3. Advertising (Google AdMob)
Somnia is free and has no in-app purchases. It shows native ads labeled “Ad” and, only if you choose to, rewarded videos to create more (an extra layer, a mix slot or the Full Night). Ads are served by Google AdMob, which may use your device's advertising ID, cookies or similar technologies to show ads, cap their frequency, measure results and detect fraud.
- In the European Economic Area, the UK and Switzerland, and in US states with privacy laws, your choice is requested through Google's consent platform (UMP). If you decline, non-personalized ads or no ads are shown.
- You can reset or delete your advertising ID in Android Settings → Privacy → Ads.
- More information: How Google uses information from sites or apps that use its services and Google Privacy Policy.
4. Your consents and how to change them
| Consent | When it is requested | How to change it |
|---|---|---|
| Terms of Use and this policy | When you first open Somnia and whenever they change materially | Stop using the app and delete your data in Settings → Your data |
| Advertising (Google UMP: GDPR in the EEA, UK and Switzerland, and US state privacy laws) | After you accept the terms, if the law in your region requires it | Settings → Ads → Ad privacy options (shown where the law requires it) |
| Sharing searches anonymously | The first time you search the catalog; off until you say yes | Settings → Your data → Share my searches |
| Publishing a mix | When you check the publishing terms box, before publishing | Make the mix private in Saved |
| Watching a rewarded video | Only when you tap “Watch a video to create more” | Don't tap it: it never plays on its own |
5. Who we share data with
- Supabase (database and anonymous authentication), as a processor.
- Google (AdMob), as an independent controller for advertising.
- Vercel (hosting for the web version).
- Authorities, only when the law requires it.
We do not sell your personal data or share it with third parties for their own marketing.
6. International transfers
Our providers may process data outside your country, including in the United States. Where applicable, they rely on recognized safeguards such as the European Commission's Standard Contractual Clauses.
7. How long we keep data
- Likes and favorite songs linked to the anonymous id: until you delete them.
- Individual play records: 7 days. After that only the song's total remains, linked to no one.
- Shared searches: 30 days. After that only aggregate counts remain, linked to no device.
- Published mixes: while they are published. If you delete your data, they remain in the library anonymously, with no link to you.
- Advertising data: according to Google's policy.
8. How to delete your data
In the app: Settings → Your data → Delete my data. This removes your likes, favorites, plays and shared searches from our server and creates a new device id. Each song's public totals are kept without identifying anyone.
Without the app: email otjhllc@gmail.com with the subject “Delete my Somnia data”. We reply within 30 days.
Uninstalling the app erases everything that was stored only on your phone.
9. Your rights
Depending on where you live (for example GDPR in Europe, CCPA/CPRA in California, LGPD in Brazil), you may request access, correction, deletion, objection, restriction and portability, and withdraw consent at any time without affecting prior processing. Write to the address in section 1. You may also complain to your local data protection authority.
10. Children
Somnia is intended for adults (18 and over). It is not directed to children or teenagers under 18 and does not knowingly collect their data. If you believe a minor has given us data, contact us and we will delete it.
11. Security
Communications are encrypted (HTTPS/TLS), the device id is stored on our server only as a hash, and database access is restricted by per-user rules. No system is perfect, but we apply reasonable measures to protect information.
12. Health
Somnia offers ambient sounds for your personal rest, focus or relaxation routine. It is not a medical device, does not diagnose or treat any condition and does not collect health data.
13. Changes
If we change this policy, we will update the date above and, if the change is material, let you know in the app.
