PFMA E6B and PFMA E6B Lite Privacy Policy
Effective date: November 10, 2026
Scope and contact
Gonzalo Astica provides PFMA E6B and PFMA E6B Lite. This policy explains how information is handled when you use the calculators, purchase or restore optional modules, or contact support. The purchase verification sections apply to PFMA E6B Lite versions that offer in-app module purchases. For privacy questions and requests, contact support.pfma@gmail.com.
Calculator data and offline use
Calculator entries, saved settings and local app data are processed on your device. We do not transmit your calculation entries or navigation coordinates to our purchase verification service. Free tools and previously verified purchased tools can be used offline. Buying modules, restoring purchases on a new installation and checking purchase validity require an internet connection. PFMA does not require a separate PFMA account.
Purchases and verification
Apple App Store or Google Play processes payments under its own terms and privacy policy. PFMA does not receive your payment card number or bank details.
When PFMA E6B Lite verifies or restores a purchase, it sends the platform, product identifier, transaction identifier and store-issued purchase proof to our verification service over HTTPS. Previous purchase proofs may also be sent to establish eligibility for a discounted package. We use this information to confirm purchase validity, unlock the appropriate modules, restore access, calculate eligible package offers and prevent fraudulent claims.
The app stores purchase proofs and verified access locally using protected platform storage. Our service stores a cryptographic fingerprint of the purchase proof and its associated product to remember fulfilled purchases and discounted packages. Verification requests are processed with the relevant store. The entitlement database does not store payment card information or the original purchase token.
Service providers and technical information
Apple and Google process store transactions and purchase verification requests. Cloudflare provides the HTTPS connection and security services used to reach our verification service. Network providers may process technical request information, including IP addresses and request metadata, to deliver and protect the service. They process information under their own applicable policies.
We do not use advertising SDKs, an advertising identifier or behavioral analytics in the PFMA E6B Lite version described here. We do not sell your personal information or use purchase information for targeted advertising.
Support and external links
If you email support, we process the information you choose to send to answer your request. Please do not send payment card numbers or bank credentials. If purchase assistance is needed, we may request information sufficient to identify and verify the relevant store purchase.
External links, including store listings, support email and the website hosting this policy, are operated under the policies of their respective providers. The calculator itself does not use advertising cookies. Cookies or advertising on external websites are governed by those websites.
Retention and deletion
We retain purchase entitlement records for as long as needed to maintain and restore purchased access, prevent fraud and meet applicable legal obligations. Support correspondence is retained as needed to resolve requests and meet those obligations. Service providers may apply their own retention policies to technical information and store records.
You can clear calculator data and settings through your device or by uninstalling the app. To request access to, correction of or deletion of information we hold, email support.pfma@gmail.com. We may need to verify the purchase or requester's identity using relevant information. Deleting entitlement records may affect our ability to restore discounted packages. Deleting app data does not delete purchase records held independently by Apple or Google; those records are managed through the relevant store.
Security and permissions
Purchase verification uses HTTPS. We take reasonable measures to protect the purchase information we handle, but no transmission or storage system can be guaranteed completely secure.
The Android Lite version prepared for this release does not request access to your photos, videos, shared audio files or shared storage. Notification permission, when requested, supports local timer alerts. PFMA does not use that permission for advertising.
Children and policy changes
PFMA is not directed to children under 13. If you believe a child has provided us with personal information, contact support.pfma@gmail.com so we can review and address the request.
We may update this policy when the app or its data practices change. Any updates will be published on this page with a revised effective date.
