Dublio Privacy Policy

1. What this policy covers

This policy applies to the Dublio app for Android and iOS (package and bundle identifier com.inceptionapps.dubstudio). This website has its own privacy notice.

2. No account, no identity

You do not register, sign in, or give us a name, e-mail address or phone number to use Dublio. We do not run a server that receives your videos, your subtitles or the dubs you make. The only identifiers involved are the ones Google’s and Apple’s services use: a random app instance ID for Firebase (section 6) and, on the free plan, your device’s advertising identifier (section 7).

3. What happens on your phone

Everything Dublio does to a video, it does on the phone:

• It writes down the speech in the video with its timing, and recognises which language is spoken.
• It translates the subtitles into the language you choose.
• It separates the speech from the music and sound effects, so only the speech is turned down under the dub.
• It tells the speakers apart, so each one can get a different voice.
• It speaks the translation with the voices installed on your phone, never with voices that need an internet connection.
• When you choose it, it makes the voice sound like each speaker’s own voice, using a few short clips of that speaker cut from the same video.

To tell speakers apart and to copy a voice, the app works out a numeric description of how each voice sounds. It is computed on the phone, used only to prepare that video, and never used to identify anyone. It is not sent to us or to anyone else.

Your videos, their sound, the subtitles and translations, the speaker clips and the voices the app makes are never uploaded by the app.

4. What the app keeps on your phone

All of the following is kept in the app’s storage on your phone. None of it is sent to us.

• Videos and subtitle files you open. On Android the app reads the file where it is, with the access you gave it in the system file picker; it does not copy the video. On iPhone, iOS hands the app its own copy of the file you pick, which is kept in the app’s private storage.
• Your lists of recent videos and subtitle files and your favourites, so you can prepare them again in another language.
• Preparations: the subtitle lines in the original and the translated language with their timings, the dub’s sound, the separated speech, which speaker says which line, and, when a speaker’s own voice is used, the short speaker clips. Each preparation keeps these in its own folder; they are not shared between videos.
• Exported files (videos, subtitle files and audio) that the app has made for you to save or share.
• Downloaded language files (section 5).
• Settings: the app’s language and appearance, how subtitles look, your preparation choices and whether the app may prepare at full speed in the background.
• The progress of each preparation, so a paused or interrupted one can continue where it stopped.
• The free-plan counter: a small record of how many free preparations you have used this calendar month and of single preparations you have bought and not used yet, with no identifiers and nothing about your videos. It is not sent to us. So that clearing the app’s data or reinstalling does not reset it, copies are also kept outside the app’s own storage: on Android in Google’s Block Store and in the system’s backup, which Google’s backup can restore when the app is installed again or on a new phone (this record is the only part of the app’s data that goes into that backup), and on iPhone in the Keychain.

5. Language files and voices

Some of the files Dublio needs to recognise, translate and speak languages are too large to come with the app. Each one is downloaded once, the first time you choose a language or an option that needs it, and the app tells you before the download starts.

• Where they come from. From the app store you installed Dublio from (Google Play or the App Store), where the store offers them, and otherwise from public file-hosting services. Like any download, the host sees your IP address and which file is requested. Nothing about you or your videos is sent. The app checks every file against a fingerprint built into the app before it uses it.
• The fast translation gets its language packs from Google. While it is used, Google’s translation component also sends Google technical information about how it works: device and app information, a per-installation identifier, the type of request, error codes and timings, as described in Google’s data disclosure for it. It never sends the text being translated.
• Phone voices belong to your phone. If a language has no voice, the app sends you to the phone’s settings, and the phone downloads the voice; the app takes no part in that download.

Once the files you use are on the phone, preparing a video needs no internet connection.

6. Usage statistics, crash reports and app settings

The app uses three Google Firebase services. Google processes this data for us.

Never sent to Firebase: file names, video titles, subtitle or dubbed text, file paths, links, or any identifier of ours for you or your device.

Test builds of the app send nothing to Firebase. In the EEA, the UK and other regions where consent is required, what usage statistics may keep follows your choices in Google’s consent form (section 7). How Google handles this data is described in the Firebase privacy information.

7. Ads, consent and the advertising identifier

On the free plan, the app may show ads supplied by Google AdMob in two places:

• Before a free preparation, a short video ad.
• In the player, a full-screen ad break from time to time. The breaks are marked on the seek bar, and none are shown in the mini player or the floating picture-in-picture window.

Whether ads are shown, and how often the player’s breaks come, are settings we can change without an app update.

To serve ads, Google uses your device’s advertising identifier (the Advertising ID on Android, the IDFA on iOS) and device information. The advertising identifier is a resettable identifier kept by the operating system, not by us. You can reset or limit it in your device settings at any time.

Consent (EEA, UK and other regions where it is required). Before ads start, the app shows Google’s consent form where the law requires your consent. Your choices are passed to Google with each ad request. If your choices do not allow ads to be requested, the app does not start ads at all. Your choices also decide what usage statistics may store: until you allow it, including when you have Pro or ads are off and the form is not shown, Google Analytics receives only signals without identifiers, and nothing is stored on your device for it. You can change your choices at any time in the app under Settings → Privacy choices; the row is shown where the law requires consent, also to Pro subscribers.

Tracking question (iOS). On iPhone, after Google’s consent form, the system asks whether the app may track you before ads start. If you decline, the IDFA is not used; you may still see ads, which are less relevant.

The app does not pass your videos, subtitles, file names or anything about what you prepare to the ads. What Google does with ad requests is governed by Google’s own policies, linked above.

Pro subscribers see no ads, neither before a preparation nor in the player.

8. Subscription, payments and the free plan

Dublio Pro is a monthly or yearly auto-renewing subscription sold through Google Play on Android and the App Store on iOS.

We never see your payment details. Card numbers, billing addresses and store account details are handled by Google and Apple and are never passed to the app. When the app needs to know whether you have Pro, it asks the store on the phone and learns only whether a subscription is active. We keep no purchase records on a server of our own. Google Analytics may record a purchase event by itself, with the product, price and currency, never payment details.

On the free plan, a single preparation can also be bought once, through Google Play or the App Store, where we offer it. The store handles the payment exactly as for the subscription; the app only learns that the purchase went through, and keeps the store’s purchase number on the phone so the same purchase is never counted twice.

The free plan’s count is kept on the phone and is not sent to us (section 4). So that the month cannot be changed by setting the phone’s clock, the app reads the current time from a server before a free preparation starts: an empty page at www.google.com, or Apple’s connection-check page at captive.apple.com where Google cannot be reached. Without an internet connection, a free preparation does not start. The request carries nothing about you or your videos; like any request, it shows Google or Apple your IP address.

9. Ratings, sharing and writing to us

Everything in this section happens only when you choose it.

• Writing to us (Settings → Write to us): the form sends nothing itself. It has no field for your e-mail address, name or phone number. Send opens your own e-mail app with the message, addressed to us, and nothing leaves your phone until you send it from there. The reply goes to the address you send from.
• Include device info is on by default and can be switched off before you send. When it is on, the e-mail ends with these lines and nothing else: app version, platform (operating system and version), device model, language (the app’s, and your phone’s when they differ), whether you have Pro, and how many videos you have prepared. They contain no identifiers, no location, no file names and nothing from your videos or subtitles. You can also edit or delete them in your e-mail app.
• We use the e-mails you send us only to answer you (see section 14 for how long we keep them).
• Rate the app opens the app’s page in Google Play or the App Store; what you write there goes to the store under your own account.
• The rating question: after a preparation or an export finishes, the app may ask how you like it, with five stars, at most once every 30 days and three times in all. The number of stars is sent to Google Analytics (section 6). With four or five stars, the store’s own review card opens; what you write there goes to the store.
• Share the app opens your phone’s share sheet with a short text and a link to the app. You choose where it goes.

10. Permissions and why they are asked for

Android

• Internet: to download language files and to reach the Google services above.
• Notifications: to show the progress of a preparation or an export while the app is in the background. Optional.
• Running in the background (a foreground service and a wake lock): so a preparation goes on with the screen off. The progress notification is shown while it runs.
• Ignore battery optimisation: asked only if you choose to let the app prepare at full speed in the background, because some phones slow background work down. Optional.
• Added by Google’s libraries: the advertising identifier (ads and usage statistics) and Google Play Billing (the subscription).

Videos and subtitle files are opened through the system file picker, which gives the app access only to the files you choose. Saving an exported file uses the system’s save dialog, where you choose the place.

iOS

• Background processing: on iOS 26 and newer a preparation can continue in the background, with its progress shown by the system. On earlier versions it continues when you return to the app.
• Background audio and picture in picture: so a video you are watching can go on in the floating window.
• Tracking (the system’s tracking question), on the free plan, for ads as described in section 7.

Not requested at all

Dublio does not ask for your location, camera, microphone, speech recognition, contacts, calendar, phone, SMS, or your photo, video or music library. The speech in a video is recognised by the app itself, on the phone, from the file you chose.

11. Device backups

If your phone’s backup is switched on, Android may include some of the app’s data, such as settings and preparations, in the backup to your own Google account, under Google’s terms. On iPhone, the app keeps its files out of iCloud Backup. The free-plan counter (section 4) can be part of a backup too: on Android through Google’s Block Store, and on iPhone with the Keychain in an iCloud or encrypted computer backup. A backup belongs to your Google or Apple account, not to us, and we have no access to it.

12. What we do not do

• We do not run a server that receives your videos, subtitles or dubs.
• We do not upload your videos, their sound, subtitles, translations, speaker clips or the voices the app makes.
• We do not send file names, titles, text or file paths to usage statistics, crash reports or ads.
• We do not use voices to identify people.
• We do not sell or rent your personal data.
• We do not require an account, and we do not build a profile about you.

13. Children

Dublio is not directed at children under 13, and we do not knowingly collect personal data from children. If you believe a child has sent us personal data in an e-mail, please contact us and we will delete it.

14. How long data is kept

• On your phone: until you delete it. Delete a preparation in the app, or clear the app’s data or uninstall it to remove everything the app stored, except the free-plan counter (section 4), which can stay and starts again from zero each month.
• Google Analytics: event data is kept for a limited time, at most 14 months.
• Crashlytics: crash reports are kept for 90 days.
• E-mails you send us: as long as we need them to answer you.

Full instructions, including how to ask about the usage data, are on the data deletion page.

15. Changes to this policy

When the app starts using a new service or sending new data, this policy changes before that version reaches you, and the date at the top of the page changes with it.

16. Contact
