Privacy Policy
Effective Date: October 26, 2026

1.Data Controller
The data controller responsible for your personal data is:
Mugen Software SIA
Registration No. 40203547797
Matisa iela 61A - 19, Riga, LV-1009, Latvia
Email: support@mugenapps.io
Mugen Software SIA ("we," "our," or "us") publishes Singabit, a voice training app for iPhone (the "App"), on the Apple App Store. This Privacy Policy explains what personal data is processed when you use the App and this website (singabit.app), why, and what choices you have. It follows the General Data Protection Regulation (EU) 2016/679 ("GDPR") and other applicable data protection laws.
2.The Short Version
- The App has no accounts and no sign-in. We never ask for your name, email address or phone number.
- Singabit listens to your singing on your iPhone. The audio is analysed on the device and never sent to us or to anyone else.
- Your recordings are saved only on your iPhone. They leave it only if you share or export them yourself.
- Your voice profile, scores and practice history sync through your own private iCloud storage, which we cannot access.
- We use Google Firebase to understand how the App is used and to fix crashes, and RevenueCat to manage Singabit Plus subscriptions.
- The App shows no ads and does not track you across other companies' apps or websites.
- We measure our own ads on Google Ads and Apple Search Ads without your advertising identifier. Outside the EEA, the UK and Switzerland, Google learns when the App is installed and when a trial or subscription starts.
- We do not sell your personal data.
3.Your Voice and Your Recordings
Microphone. The App uses your iPhone's microphone, with your permission, to detect the pitch you sing. Pitch detection runs entirely on your iPhone. We never receive the audio, and we do not use your voice to identify you or create a voiceprint.
Recordings. Your takes are recorded so that you can listen back to them. They are stored only in the App's storage on your iPhone. The App keeps the last 10 recordings of each exercise plus your best one, and deletes older recordings automatically. Your scores and charts stay.
Recordings are included in your iPhone's backups (iCloud Backup or a backup on your computer), which Apple or your computer stores under your control. Restoring a backup brings them back.
Sharing and exporting. You can share a take as an image or a short video, or export your data, through the iOS share sheet. Whatever you share goes where you choose to send it, such as a messaging app or Photos, and that service's own privacy policy then applies. Saving to Photos uses add-only access: the App cannot see your photo library.
4.Data That Stays on Your Device or in Your iCloud
Your practice data. The App stores the following on your iPhone:
- your voice profile: voice type, vocal range, goals, experience level and note-name preference
- your takes: date, exercise, keys, tempo, score, stars, the result for each note, the pitch line, and the file name of the recording
- your range tests and practice days (for your streak)
iCloud sync. If you are signed in to iCloud and iCloud is on for Singabit, Apple syncs your practice data (not your recordings) to the App's container in your private iCloud database, so that it appears on your other devices. Apple stores this data under its own privacy policy. As the developer, we have no access to your private iCloud database. You can turn iCloud off for Singabit in your iPhone's settings under [your name] › iCloud; the App then keeps your data on this iPhone only.
Settings. Your reminder time, practice mode, sound settings and headphone delay calibration are stored on this iPhone only and are not synced.
Reminders. The daily practice reminder and the reminder before a free trial ends are scheduled by the App on your iPhone (local notifications). No push service is involved, and no notification token is sent to us.
This data is deleted when you delete it in the App (Settings › Your data › Delete all my data), which also removes it from iCloud and, at their next launch, from your other devices. Deleting the App removes the data on that iPhone, but not the copy in iCloud.
5.Data Processed When You Use the App
Usage and analytics data (Google Analytics for Firebase). We collect information about how the App is used, including:
- onboarding steps, the goals you pick and your answer to the microphone permission
- range test results (your lowest and highest note) and your voice type
- exercises started, finished or left early, with the exercise, score, stars and how many keys were sung
- lessons opened and finished, and quiz answers
- reminders turned on or off, with the hour chosen
- purchase screen views, plan choices and purchase outcomes
- sharing actions (what kind of item was shared, in which format and to which app, never the item itself)
- general attributes: experience level, goals, voice type and plan (free, trial, Plus or expired)
- app version, device model, operating system version, language, and a randomly generated app instance ID
- approximate location (country, region or city), derived from your IP address; Google Analytics does not store the IP address itself
Google signals and ads personalisation are turned off for the App. Analytics data is linked only to the random app instance ID, never to your name or Apple Account.
Crash and diagnostic data (Firebase Crashlytics). If the App crashes or hits certain errors, such as a recording that could not be saved, we receive a report. It contains the technical details of the error, your device model and operating system version, the app version and a random installation identifier. It never contains audio.
App configuration (Firebase Remote Config). The App downloads its configuration from Firebase, which lets us adjust features without an update. This uses a random Firebase installation ID, the app version, the language and the country.
Purchases (Apple and RevenueCat).
- Apple processes all payments. We never receive your payment card or billing details.
- RevenueCat helps us check and restore your Singabit Plus subscription. It processes a random app user ID, your purchase and subscription history (product, price, currency, transaction dates and receipt data), and basic device and app information.
- RevenueCat also receives the App's random analytics ID, so that it can report subscription events, such as trial starts, renewals and cancellations, to Google Analytics for Firebase. This lets us measure revenue.
- We sometimes compare different versions of the purchase screen or different prices. RevenueCat assigns each test group at random, using the random app user ID.
Install attribution (Apple Search Ads). When the App is first opened, it reads an attribution token from Apple's AdServices framework, and RevenueCat sends it to Apple to learn whether the App was installed from an Apple Search Ads campaign, and if so which campaign and keyword. This does not use your device's advertising identifier and does not involve tracking.
Advertising measurement (Google Ads). We advertise the App with Google Ads. Outside the European Economic Area, the United Kingdom and Switzerland, the App lets Google Analytics for Firebase tell Google Ads when the App is first opened and when you reach steps such as finishing your first exercise or starting a free trial or subscription (with its price), so that we can see which ads bring new users and improve our campaigns. This uses the App's random analytics ID, Apple's privacy-preserving SKAdNetwork attribution and Google's on-device conversion measurement, never your device's advertising identifier. Ads personalisation and remarketing are turned off, so this data is not used to show you ads in other apps or on websites. In the EEA, the United Kingdom and Switzerland, this sharing is off; the App decides by your App Store country or, if that isn't available, your device's region.
Data Apple shares with us. If you have agreed to share analytics with app developers in your iOS settings, Apple may provide us with aggregated usage and crash statistics.
Support requests. If you contact us, we receive your email address and whatever you include in your message.
The App does not use the camera, your contacts or your precise location, and it does not ask for these permissions. The App does not use your device's advertising identifier (IDFA) and does not ask for permission to track.
6.This Website
This website (singabit.app) is hosted by Cloudflare. To deliver and protect the site, Cloudflare processes your IP address and technical request data, such as your browser type and the page requested.
We measure visits with Cloudflare Web Analytics. It does not use cookies or identify individual visitors. It counts page views, referring websites, countries and device types in aggregate.
The App Store buttons on this site link to Apple's App Store with a campaign tag that tells us which button was used. Once you are on the App Store, Apple's privacy policy applies.
The website sets no tracking or advertising cookies and shows no ads. Cloudflare may set a strictly necessary security cookie to protect the site from automated attacks.
7.Legal Basis for Processing
We process your personal data on the following legal bases under Article 6 of the GDPR:
- Performance of a contract (Art. 6(1)(b)). Providing the App, its configuration and iCloud sync, and processing and restoring Singabit Plus subscriptions.
- Legitimate interests (Art. 6(1)(f)). Analytics, crash reporting, purchase screen tests, install attribution and measuring our own ad campaigns, used to keep the App stable, improve it and understand which of our efforts bring new users. Also hosting and protecting this website. Our interests are balanced against your rights, and you can object at any time (section 11).
- Consent (Art. 6(1)(a)). Notifications, which the App sends only if you allow them. You can withdraw consent at any time in the App's Settings or in iOS Settings › Notifications.
- Legal obligation (Art. 6(1)(c)). Keeping records required by accounting and tax laws, and responding to lawful requests from authorities.
8.How We Share Your Information
We do not sell your personal data. We share data only with the following service providers, which process it on our behalf to operate the App and this website:
- Google (Firebase and Google Ads): analytics, crash reporting, configuration, and measuring our Google Ads campaigns. Google's privacy policy: https://policies.google.com/privacy. Firebase privacy information: https://firebase.google.com/support/privacy
- RevenueCat: subscription management. https://www.revenuecat.com/privacy
- Apple: App Store distribution, payment processing, install attribution and iCloud. https://www.apple.com/legal/privacy/
- Cloudflare: website hosting and website analytics. https://www.cloudflare.com/privacypolicy/
We may also disclose information if the law, a court order or a legal process requires it. We may also disclose it to protect the rights, property or safety of Mugen Software SIA, our users or others. If the App is transferred to another company, for example in a sale or merger, the related data may be transferred as part of that transaction, subject to this Privacy Policy.
US state privacy laws. We do not sell personal information, and we do not share it for targeted advertising. The App shows no ads. Data shared with Google Ads is used only to measure our own campaigns, with ads personalisation turned off.
9.International Data Transfers
Our service providers (Google, RevenueCat, Apple and Cloudflare) may process your data in the United States and other countries outside the European Economic Area (EEA). Where data is transferred outside the EEA, appropriate safeguards are in place, such as:
- European Commission adequacy decisions
- Standard Contractual Clauses approved by the European Commission
- the EU-U.S. Data Privacy Framework, where applicable
You may request more information about these safeguards by contacting us.
10.Data Retention
- On your device: your practice data and settings stay until you delete them or delete the App. Recordings are limited to the last 10 of each exercise plus your best, as described in section 3.
- In your iCloud: your practice data stays until you delete it in the App or in your iCloud settings.
- Analytics data: kept for up to 14 months, after which Google Analytics deletes it automatically. Aggregated reports that cannot identify you may be kept longer.
- Crash reports: kept for 90 days.
- Purchase records: kept for as long as needed to provide Singabit Plus and as required by accounting and tax laws.
- Support emails: kept for as long as needed to resolve your request and for a reasonable period afterwards.
- Website requests: Cloudflare keeps them under its own policies; Web Analytics keeps only aggregated counts.
11.Your Rights
Under the GDPR, you have the following rights regarding your personal data:
- Right of Access (Art. 15): request a copy of the personal data we hold about you.
- Right to Rectification (Art. 16): request correction of inaccurate data.
- Right to Erasure (Art. 17): request deletion of your personal data.
- Right to Restriction (Art. 18): request that we limit the processing of your data in certain circumstances.
- Right to Data Portability (Art. 20): receive your data in a structured, machine-readable format.
- Right to Object (Art. 21): object to processing based on legitimate interests.
- Right to Withdraw Consent: withdraw consent at any time, without affecting the lawfulness of processing before the withdrawal.
Most of your data never reaches us, so you can act on these rights directly in the App:
- Export: Settings › Your data › Export my data gives you a file with your history and scores, range tests and settings (JSON) and your recordings (M4A audio).
- Delete: Settings › Your data › Delete all my data deletes your data on this iPhone and in iCloud, and starts a new random analytics ID.
- Notifications: turn reminders off in the App or in iOS Settings › Notifications.
Because the App has no accounts, the data our providers hold is linked to random identifiers, not to your name. We may therefore not be able to identify which data is yours from an email alone. We will explain what information we need to find it.
To exercise any of these rights, contact us at support@mugenapps.io. We will respond within 30 days.
Right to Lodge a Complaint. If you believe your data protection rights have been violated, you have the right to lodge a complaint with the Data State Inspectorate of Latvia (Datu valsts inspekcija), Elijas iela 17, Riga, LV-1050, Latvia, www.dvi.gov.lv, or with your local supervisory authority.
12.Children's Privacy
Singabit is made for a general audience and is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child under 13 has used the App and data about them has been collected, contact us and we will delete what we can. You can also use Delete all my data in the App, which removes the data on the device and in iCloud and starts a new analytics ID.
13.Data Security
- Data sent between the App, this website and our service providers is encrypted in transit.
- On-device data is protected by iOS app sandboxing and your device's security settings.
- iCloud data is protected by Apple's iCloud security, including encryption.
- Our service providers apply industry-standard security measures.
No method of transmission or storage is completely secure, but we work to protect your information.
14.Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy on this page and, where appropriate, in the App. The "Effective Date" at the top shows when it was last revised.
