1) Overview
Conversion Rate Calculator is a simple utility app that performs calculations on your device. In this version, we do not collect, store, share, or sell personal information. No account is required, and no data is transmitted to our servers.
If a future update introduces features that process personal data (e.g., analytics, crash reporting, ads, or cloud sync), we will update this Privacy Policy, the Google Play Data Safety form, and provide an in-app notice where required.
2) What information we (don’t) collect
Personal data (name, email, phone, identifiers): Not collected
Sensitive data (health, financial, biometric, messages, photos, precise location): Not collected
Device or usage analytics (IP, device model, app events): Not collected
Advertising ID: Not collected or used
User-generated content: The numeric values you enter (e.g., visits, conversions) are processed locally and are not sent to us
3) How the app works
Calculations run on device.
Results and inputs remain in the app’s temporary memory unless you save or screenshot them using your device OS.
There is no sign-in, no account system, and no server-side storage by SparkX Marketing.
4) Permissions
This version does not request any Android runtime permissions beyond those required by the operating system to run the app. If a future version needs a permission, we will:
Ask for your consent within the app,
Explain the purpose in-app, and
Update this policy before release.
5) Third-party services (SDKs, analytics, ads)
We do not use any third-party SDKs for analytics, advertising, attribution, or crash reporting in this version.
If we add any third-party services later, we will list them here and describe what data they process and for what purpose.
6) Data retention & deletion
Since we do not collect personal data, there is nothing retained on our servers. Any values you enter live on your device and are cleared when you reset the fields or uninstall the app.
7) Children’s privacy
The app is for a general audience and is not directed to children. We do not knowingly collect personal data from children. If you believe a child has provided personal data to us, contact us at ahsan@sparkxmarketingltd.com and we will address it promptly.
8) Security
We do not maintain user accounts or server-side databases for this app. Should we add cloud features in the future, we will implement reasonable technical and organizational measures appropriate to the data we process and will update this section accordingly.
9) International use & transfers
We do not transfer personal data across borders because we do not collect it. If future features involve processing personal data, we will disclose any cross-border transfers and applicable safeguards.
10) Your rights
Because we do not collect or store personal data, requests such as access, correction, portability, or deletion generally do not apply to this app. If you have any questions, contact ahsan@sparkxmarketingltd.com and we’ll clarify based on your situation and local law.
11) Changes to this policy
We may update this policy to reflect changes to the app. When we do, we will change the Effective date above and publish the revised version at the same URL. Material changes may also appear in an in-app notice.
