Convela Privacy Policy

Effective date: 2026-11-10

Convela is a unit converter: it converts length, area, weight, volume, temperature, speed, time, cooking measures, fuel economy, pressure, energy, power, data, angle and blood sugar units, lets you pin the conversions you use most, keeps a short history, converts currency with exchange rates you type in yourself, and offers daily conversion tips and a home screen widget (the "app"). It is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Convela has no account system and we do not run a server for it. Every conversion is calculated on your device.

Data stored on your device

Your pinned conversions, your recent conversions (unit and value), the last value you typed in each category, the currency rates you enter, your chosen cooking ingredient and your settings (decimal places, thousands separator, inch fractions, reminders, theme) are stored only on your device. They are not sent to us. Uninstalling the app deletes this data from your device. If device backup is turned on, Android's standard app backup may include this data in your own Google account backup. That backup is controlled by you and Google, not by us.

Currency rates

Convela does not download exchange rates. The currency screen uses only the rates you type in, and it shows the date you entered each one. The app does not contact any exchange-rate service.

Copying and sharing a result

When you tap a result, the app copies it to your device's clipboard. When you tap Share, the app opens the Android share sheet with a short text of the result. Nothing is sent unless you choose an app to share it with; what happens next is up to that app.

Permissions the app asks for and why

• Notifications (optional). Used for a morning and evening conversion tip. You can decline and every feature still works.
• Run at startup. Lets reminders come back after your phone restarts or the time zone changes.
• Vibration. Used for reminder notifications (you can turn it off).
• Internet access, network state and the advertising identifier (AD_ID). Used only by the advertising components described below. Every conversion in the app works offline.

The app does not request your location, the camera, microphone, storage or media permissions, your contacts, or access to health data.

Information collected automatically

When you use the app, third-party SDKs used for advertising may collect some information automatically, including:

• Your device's Internet Protocol (IP) address, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as your device's operating system and model, and ad performance data

The advertising SDK collects this information and shares it with Google (AdMob) and its advertising partners for advertising, analytics, fraud prevention, security and compliance. It is encrypted in transit. The app itself does not send your conversions, history, pinned pairs, currency rates or settings off your device, and we do not link the advertising data to them.

Advertising

The app shows advertisements from Google AdMob:

• a banner at the bottom of the screens
• an ad when the app starts from the launcher
• full-screen ads only at a few moments: when you open a category from the list of all conversions, and after you save a currency rate
• an ad in the exit dialog
• optional video ads you can choose to watch from Settings to see fewer ads for 24 hours

A full-screen ad never appears when you open a pinned conversion, a recent conversion, a search result, the widget or a notification, while you are typing, or when you switch tabs. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. In the European Economic Area (EEA), the United Kingdom and other regions where required, the app shows a consent form through Google's User Messaging Platform (UMP) before personalized advertising data is used. If you decline, you are shown non-personalized ads instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen.

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Accuracy notice

Conversions use standard published factors and are rounded for display. Cooking conversions between cups and grams use typical average densities for each ingredient, so real kitchen results can differ. Blood sugar conversion is a unit calculation only and is not medical advice. Check critical values (medical, engineering, legal or financial) against an authoritative source.

Children

Convela is a general-audience app and is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device, so you control it directly: you can unpin conversions, clear history and delete rates in the app, and uninstalling the app removes everything the app stored. Depending on where you live (for example under the GDPR in the EEA/UK or the CCPA in California), you may also have rights over data processed by advertising SDKs. You can exercise your ad choices through the consent form and your device's ad settings described above.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
