This policy explains what the PowerPlanner mobile app ("the App"), published by Appentium ("we", "us"), collects, why, and what control you have over it. It applies to the App and to powerplanner.appentium.com.
- You can use every calculator in the App without an account.
- Your calculations, plans and tariff settings are stored on your device unless you sign in to sync them.
- Location is only requested for the solar forecast, and only when you use it.
- We do not sell your personal information, and we do not track you across other companies' apps or websites.
- You can delete your account and everything attached to it from inside the App.
1. Information you give us
- Account details. If you choose to sign in with Apple or Google, we receive an account identifier and, depending on what you allow, your name and email address. With Sign in with Apple you may hide your real email; we work fine with the relay address.
- Profile. An optional display name, country and profile photo.
- Community content. Posts, comments, community requests, and any images you attach. Also the reports you file and the users you block.
- Calculator inputs. Appliance wattages, battery and panel figures, electricity tariffs, bills and outage logs you record.
- Support correspondence. Anything you send us by email.
2. Information collected automatically
- Usage and device data. Screens opened, features used, app version, device model, operating system, language and coarse region — collected through Google Analytics for Firebase to understand how the App is used.
- Crash and performance data. Stack traces, device state at the time of a crash, and timing traces, via Firebase Crashlytics and Firebase Performance Monitoring.
- Log data. If the App errors, diagnostic information may be recorded, which can include your device's IP address as handled by our service providers.
- Advertising identifiers. See section 6.
3. Location
Location is optional and requested only when you open the Solar Forecast or ask the App to detect your site automatically. Your coordinates are used to fetch local sunlight and weather data and to look up a place name for display.
We send those coordinates to Open-Meteo for the forecast and to OpenStreetMap Nominatim for reverse geocoding. We do not store a history of your locations on our servers, and the App works without location — you can enter a location manually instead.
4. AI-assisted features
The AI Energy Advisor, AI plan generation and electricity-bill scanning are powered by the Google Gemini API.
- What you type into the advisor, and the system figures relevant to your question, are sent to Google to generate a response.
- When you scan a bill, the photograph is sent directly to the Gemini API to read the figures from it. We do not upload bill photos to our own storage or keep them on our servers; only the values extracted from the bill are saved, and only on your device unless you sync.
Please do not enter sensitive personal information into the AI features. Google's handling of this data is governed by its own terms; see the Gemini API terms.
5. Purchases
Payments are processed entirely by the Apple App Store or Google Play. We never see or receive your card details. We use RevenueCat to validate receipts and to know whether your PowerPlanner Pro access is active. RevenueCat receives a purchase identifier, the product bought, your country and, if you are signed in, your account identifier, so that access follows you across devices.
6. Advertising and your choices
The free tier of the App shows advertising supplied by Google AdMob. Ads are removed entirely for PowerPlanner Pro users.
On Android, Google's advertising ID may be used to serve and measure ads, subject to the consent choice described below and to your device settings — you can reset or delete that ID under Settings → Google → Ads.
Where required by law — including in the EEA, the UK and Switzerland — we show a consent form from Google's User Messaging Platform before serving personalised advertising. You can reopen that form and change your choice at any time from the App's settings, under the ad privacy options.
7. How we use information
- To provide the calculators, forecasts, plans and community features.
- To sync your saved plans across your devices when you are signed in.
- To keep the community safe — reviewing reports, removing content that breaks our rules, and enforcing blocks.
- To deliver optional notifications you have opted into.
- To diagnose crashes, fix bugs and improve performance.
- To understand which features are used, so we can decide what to build.
- To show advertising that funds the free tier, and to process purchases.
- To comply with legal obligations and enforce our Terms of Use.
8. Legal bases (EEA/UK users)
- Performance of a contract — running your account, syncing your plans, delivering purchases.
- Consent — location, notifications, and personalised advertising. You can withdraw consent at any time.
- Legitimate interests — keeping the service secure and functioning, moderating the community, and understanding aggregate usage.
- Legal obligation — where we must retain or disclose information by law.
9. Who we share information with
We do not sell personal information. We share it with the service providers below, only as needed to run the App:
| Provider | Purpose | Policy |
|---|---|---|
| Google Firebase (Auth, Firestore, Storage, Functions, Remote Config) | Accounts, saved plans, community content, account deletion | Link |
| Google Analytics for Firebase | Usage analytics | Link |
| Firebase Crashlytics & Performance | Crash and performance diagnostics | Link |
| Google AdMob & User Messaging Platform | Advertising and consent management | Link |
| Google Gemini API | AI advisor, AI plans, bill scanning | Link |
| Sign in with Apple | Optional authentication | Link |
| Google Sign-In | Optional authentication | Link |
| RevenueCat | Purchase validation and entitlements | Link |
| OneSignal | Push notifications | Link |
| Open-Meteo | Weather and solar irradiance forecasts | Link |
| OpenStreetMap Nominatim | Reverse geocoding of coordinates | Link |
We may also disclose information where legally required, to investigate abuse or fraud, or as part of a merger or acquisition — in which case we will say so before your information becomes subject to a different policy.
10. Community content is public
Anything you post in the Community — including your display name, profile photo and any images you attach — is visible to other users of the App. Please do not post information you would not want to be public. Content you report, and moderation decisions, are visible to our moderators.
11. Retention and deletion
Calculations, plans and settings stay on your device until you delete them or uninstall the App. If you are signed in, synced copies are kept until you delete them or delete your account.
You can delete your account at any time from within the App (More → Delete account). This runs a server-side deletion that removes:
- your community topics, replies and community requests;
- reports you have filed;
- your user record and everything under it, including saved plans and systems;
- your stored files, including your profile photo and image attachments;
- your sign-in account itself.
Deletion is permanent and cannot be undone. Backups and third-party diagnostic logs may persist for a limited period before expiring. Purchases are held by the app store, not by us, and are unaffected by deleting your account.
12. Your rights
Depending on where you live, you may have the right to access, correct, export, restrict or delete your personal information, to object to certain processing, and to withdraw consent. Users in the EEA/UK may also lodge a complaint with their local data protection authority. Users in California may request details of the categories of information collected and disclosed, and we do not sell or share personal information as those terms are defined by the CCPA/CPRA.
Most of these you can exercise directly in the App. For anything else, contact us at info@appentium.com and we will respond within the period required by applicable law. We do not discriminate against anyone for exercising these rights.
13. Children's privacy
PowerPlanner is not directed at children. We do not knowingly collect personal information from anyone under 13 (or the minimum age of digital consent in your country). Creating an account requires you to be at least that age. If you believe a child has provided us with personal information, contact us and we will delete it.
14. Security
Data in transit is encrypted, access to stored content is restricted by server-side security rules, and payment details never reach us. That said, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
15. International transfers
Our service providers operate globally, so your information may be processed in countries other than your own, including the United States. Where required, we rely on the safeguards those providers put in place, such as the European Commission's standard contractual clauses.
16. Links to other sites
The App and this site link to services we do not operate. We are not responsible for their content or privacy practices, and we encourage you to read their policies.
17. Changes to this policy
We may update this policy as the App changes or the law requires. The "Last updated" date above will change, and material changes will be notified in the App or by other reasonable means.
