Privacy Policy
DataStory Studio · Last updated 23 August 2026
DataStory Studio has no accounts, no analytics and no crash reporting. Everything you make stays on your device. The one thing that reaches outside it is optional advertising: the app shows a rewarded video ad only when you choose to watch one, and it asks your permission before any ad loads.
What we collect
We collect nothing about you ourselves. There is no sign-up and no login, we run no server that holds your data, and we do not use analytics or crash reporting. The only third-party component in the app is Google AdMob, which serves the optional rewarded ads described below and collects data of its own under Google's policies when an ad is shown.
What stays on your device
- Datasets you create or import. Stored on your device only.
- Videos you export. Stored on your device until you delete them, which you can do individually or all at once from Settings.
- Music you import. Copied into the app's own storage on your device.
- Your preferences — chosen language, whether you have seen the introduction, and which stories you have downloaded.
Deleting the app removes all of it. We keep no copy, because we never receive one.
Advertising
DataStory Studio is free. Exporting videos spends points, and one way to top up your balance is to watch a short rewarded video ad. This is always your choice — ads appear only when you tap to watch one. There are no banners, no interstitials, and nothing that plays on its own.
The ads are served by Google AdMob. To show them, AdMob may collect information such as device identifiers made available by iOS, general device and network details, and interaction with the ad, and may use it to measure and personalise advertising. That processing is governed by Google's advertising policies, not by us. We do not receive this information, and nothing you create in the app — your data, your charts, your videos — is ever shared with AdMob or any advertiser.
Your privacy status is checked before any ad loads. On launch, the app asks Google's consent system whether a privacy choice is required and presents Google's form when applicable. No advertising SDK starts and no ad is requested until Google reports that ads may be requested. Where required, you can review or change your choice from the app's privacy options. If you decline personalised ads, you can still watch rewarded ads and earn points; they simply are not tailored to you.
For attribution — measuring, without identifying you, whether an ad led to an install — the app supports Apple's SKAdNetwork, a privacy-preserving system that reports aggregate results to Apple and returns no personal data to us.
When the app uses the internet
Apart from loading a rewarded ad when you ask for one, the app makes network requests in two situations, and no others.
Story data — only when you ask. When you tap Check for updates on the Stories screen, pull to refresh, or use the same option in Settings, the app downloads publicly available statistics from a public GitHub repository. This never happens on its own: there is no story download on launch and no background refresh.
Supported version check — once, when the main screen opens. After the app has finished opening, once per session and only if you are already online, it reads one small file from the same public repository. That file says which versions of the app are still supported, so that a version with a serious problem can be told to update rather than left running quietly.
The request sends nothing about you. It asks for a fixed web address and reads the answer — no version number, no device details, no identifier, nothing about what you have made. The comparison happens on your device, after the file arrives. The answer is saved on your device so the app still knows where it stands when it is offline, and it is used the next time you open the app rather than interrupting the session you are in.
Neither request sends personal information, and neither sends anything about your data, your videos or your usage. As with visiting any web page, GitHub receives the standard information any web server does, including your IP address, and handles it under GitHub's privacy statement. We receive nothing.
Permissions
- Photo library — add only. Requested only when you choose "Save Video" from the share sheet. The app can add a video you just made; it cannot read your library.
- Notifications. Optional. Used only to tell you that a video you asked for has finished rendering.
- Files. Only the specific file you pick when importing a CSV or an audio track.
The app does not use your microphone, camera, contacts, calendar, location or health data.
If you email us
Contacting support is entirely your choice. If you do, we receive your email address and whatever you write. The app can pre-fill your app version, device model, iOS version and region to help us reproduce a problem — you can see this before sending and delete any of it. We use what you send only to answer you, and we do not add you to any mailing list.
Children
DataStory Studio is not directed at children under 13, and we do not knowingly collect information from anyone. We ourselves hold nothing about a child to delete. The advertising described above is not designed for children, and if you decline personalised advertising in the available privacy choices, ads are not personalised.
Your rights
Privacy laws including the GDPR, the CCPA and India's Digital Personal Data Protection Act give you rights to access, correct, export and delete personal data a company holds about you. We ourselves hold none, so there is nothing for us to return or erase. Any data collected in connection with advertising is held by Google; you can exercise your choices over it through the consent and privacy options in the app and under Google's policies. The data on your device is yours: exportable as CSV and video files at any time, and deletable from within the app or by removing it.
Changes
If this policy changes, the updated version will be posted here with a new date. If a future release ever collects anything, that will be stated plainly here and in the App Store listing before it ships.
