Privacy Policy for CivilCalc Pro
CivilCalc Pro mainly stores your project and calculation data on your device. Optional features introduce third-party processing: Google Drive backup uses your Google account only if you enable it, Google Play handles purchases and subscriptions, Google Mobile Ads supports the free tier, and website hosting may generate standard request logs. We do not sell your project content or Google Drive backup content for money.
1. Scope and controller
This Privacy Policy explains how CivilCalc Pro ("CivilCalc Pro," "we," "us," or "our") handles information when you use the CivilCalc Pro Android application and the civilcalcpro.com website.
For privacy and legal inquiries, contact contact@civilcalcpro.com. For app support, contact support@civilcalcpro.com.
Important: CivilCalc Pro does not currently require you to create a separate CivilCalc Pro account. Most app content stays on your device unless you actively choose features such as Google Drive backup, export, sharing, advertising-supported usage, or Google Play purchases.
2. Information we collect
The information involved depends on the features you choose to use.
| Category | Examples | When it is involved |
|---|---|---|
| Project, calculation, and settings content | Project names, manually entered locations, notes, calculator inputs, results, favorites, saved defaults, theme and unit preferences, and onboarding status | When you use the app, save calculations, create projects, or save settings |
| Google account information for backup | Google account email address, display name, and profile photo URL | Only if you choose to connect a Google account for backup |
| Backup credentials and backup file data | Access tokens, locally stored long-term backup credentials or tokens, backup preferences, backup timestamps, backup file identifiers, and backup file contents containing your CivilCalc Pro data | Only if you choose Google Drive backup |
| Purchase and entitlement information | Product identifiers, subscription or purchase status, pricing metadata, restore status, and locally cached entitlement timestamps | When you use Google Play billing, restore purchases, or the app checks premium access |
| Advertising and consent information | Ad requests, ad impressions, clicks, reward completion events, consent status, privacy-choice status, IP address, device and account identifiers, app interaction data, and diagnostics handled by Google Mobile Ads and related services | When the ad-supported version of the app loads or displays ads, or when ad privacy choices are shown |
| Device, network, and permission information | Internet reachability checks, device or platform context needed for backup, purchases, ad loading, and notification-permission status | When online features are used or checked |
| Notifications | Backup-progress notifications and related notification-permission state | Only if your device grants notification permission |
| Export and sharing actions | Generated PDF, CSV, or text exports and information you choose to pass into your device's share sheet | Only when you export or share |
| Support communications | Your email address, name, and the content of messages or attachments you send us | When you contact support or send privacy or legal requests |
| Website request data | Standard web request logs such as IP address, user agent, referrer, and request metadata handled by the site host | When you visit civilcalcpro.com |
Information you enter into the app
Project names, typed locations, notes, calculation inputs, results, favorites, and settings are content you choose to create or save in the app. By default, these are stored locally on your device so you can reopen and manage your work.
Information we do not need for core local use
You can use the app's local calculator and storage features without creating a separate CivilCalc Pro account. Google account information is involved only if you decide to connect Google Drive backup.
Payments
Payments are processed by Google Play. CivilCalc Pro does not collect or store your full payment card number. We may receive or store purchase status and entitlement information necessary to unlock paid features, restore purchases, or verify access.
3. How we use information
We use information only for the purposes described below.
| Purpose | Examples | Typical legal basis where applicable |
|---|---|---|
| Provide the app's core functions | Run calculators, save projects, reopen history, remember settings, and generate results | Performance of the service you request; legitimate interests in operating the app |
| Provide optional backup and restore | Connect your Google account, create backups, restore prior backups, delete the current cloud backup, and maintain the backup connection you requested | Your consent or choice to enable the feature; performance of the requested service |
| Process purchases and subscriptions | Unlock premium features, restore purchases, validate access, and reduce fraud or abuse | Performance of a contract; legitimate interests; legal obligations where applicable |
| Serve, measure, and protect ads | Display interstitial or rewarded ads in the free tier, show privacy-choice flows where required, and confirm when rewarded access has been completed | Legitimate interests and, where required by law, consent |
| Respond to requests and support messages | Reply to support, privacy, or legal inquiries and document how requests were handled | Legitimate interests; legal obligations where applicable |
| Maintain, secure, and improve the service | Troubleshoot backup failures, maintain service integrity, investigate misuse, and keep website hosting operational | Legitimate interests |
4. Google account and Google Drive backup data
CivilCalc Pro requests Google account access only if you choose to enable backup. That feature is intended to let you back up and restore your CivilCalc Pro data using your own Google account.
- We use Google account information such as your email address, display name, and profile photo URL to show which account is connected for backup and to maintain the backup connection on your device.
- We use the Google Drive application-data area only to create, read, update, restore, or delete CivilCalc Pro backup files associated with the app.
- Backup files can include your projects, saved calculations, favorites, settings, and onboarding state.
- To support optional background or headless auto-sync behavior, the app stores backup-related credentials or tokens and related backup metadata locally on the device.
- Connecting a Google account for backup does not create a separate CivilCalc Pro account with us.
- We do not use Google Drive backup data for advertising, data brokerage, or unrelated profiling.
- We do not sell your Google Drive backup content for money.
Backup content can include personal or project information that you choose to type into the app, such as project names, manually entered locations, notes, calculation inputs, results, and settings. Only enable backup if you are comfortable storing that information in your own Google account's app-specific Drive storage.
5. Advertising and ad privacy choices
The free tier of CivilCalc Pro may use Google Mobile Ads, including interstitial and rewarded ad formats. Depending on your region, device state, and legal requirements, the app may also present ad-consent or privacy-choice flows at launch and may expose a privacy-choices entry point in Settings.
- Advertising providers may process data such as IP address, general location derived from IP, device or account identifiers, app interaction events, and diagnostics according to their own policies and service terms.
- Rewarded ads may be used to unlock specific actions in the free tier unless you hold a paid entitlement that removes that requirement.
- You can use device and platform controls to limit certain advertising identifiers or personalization where those controls are offered.
7. Retention and deletion
- Local app data: retained on your device until you edit or delete it in the app, clear app storage, or uninstall the app.
- Backup connection details and locally stored backup credentials: retained on your device while backup remains connected, until removed, app storage is cleared, or the app is uninstalled.
- Google Drive backup files: retained in your Google account's app-specific storage until replaced, deleted from within the app, or otherwise removed from that account. Disconnecting backup in the app does not by itself guarantee deletion of an existing cloud backup file.
- Purchase and entitlement records: retained locally as needed to manage access, restoration, and fraud prevention, subject to Google Play's own records and retention.
- Support emails and attachments: retained for as long as reasonably necessary to respond, document requests, resolve disputes, or satisfy legal obligations.
- Website request logs: retained according to the hosting provider's practices.
Deletion controls
Because CivilCalc Pro does not currently maintain a separate first-party account system, your primary deletion controls are in the app and on your device. You can delete local content, clear app storage, disconnect backup, delete the current cloud backup from the app's backup settings, uninstall the app, and manage subscriptions through Google Play. For information primarily held by Google or another provider under your own account, you may also need to use that provider's own controls.
8. Security
We use reasonable administrative, technical, and organizational measures intended to protect information used by the app and website. Online requests to third-party services are intended to use the transport protections offered by those services and platforms, but no system is perfectly secure and no method of transmission or storage can be guaranteed to be completely secure.
Your local app data is primarily protected by your device and operating system controls. You are responsible for safeguarding your device, your Google account, and any exported files you share outside the app. A rooted, jailbroken, or otherwise compromised device can reduce the effectiveness of local protections.
9. Your choices and rights
In-app and device choices
- You can edit or delete project content and saved calculations within the app.
- You can clear local app data by deleting content in the app or clearing app storage on your device.
- You can disconnect Google Drive backup from the app.
- You can delete the current cloud backup from the app's backup settings.
- You can manage notification permission in your device settings.
- You can manage subscriptions through Google Play.
- You can choose whether to export or share files outside the app.
Advertising choices
Depending on your jurisdiction, device, and Google settings, you may be able to limit certain advertising processing through platform, device, or Google account controls. When required, the app may also provide an in-app ad privacy or privacy-options entry point in Settings so you can revisit relevant ad choices.
Legal rights that may apply to you
Depending on where you live, you may have rights such as access, correction, deletion, portability, withdrawal of consent, restriction, objection, or the right to complain to a regulator. These rights are not absolute and can depend on the legal basis and the nature of the data involved.
To make a request, email contact@civilcalcpro.com and describe your request and the email or account details relevant to it. If the requested data is held primarily by Google, Google Play, or another third party under your own account, you may also need to use that provider's own controls.
California notice
If California law applies to you and CivilCalc Pro qualifies as a covered business for the relevant processing, California residents may have rights such as the right to know, delete, correct, and non-discrimination, and in some cases rights relating to the sale, sharing, or limiting of sensitive personal information. CivilCalc Pro does not sell project content or Google Drive backup content for money.
10. Children's privacy
CivilCalc Pro is not directed to children under 13. We do not knowingly collect personal information directly from children under 13. If you believe a child provided personal information to us in a way that should not have happened, contact contact@civilcalcpro.com so we can review the issue.
11. Changes to this Privacy Policy
We may update this Privacy Policy from time to time. If we make material changes, we may update the date above, update the policy in the app or on the website, and where required by law or platform rules, seek renewed consent or provide additional notice before using information in a materially different way.
