Privacy Policy for Drywall Estimator
Effective Date: July 3, 2026 Developer: Muhammad Ilyas (Mobilia Apps) Contact: muhammadilyas15@gmail.com Application: Drywall Estimator (com.ilyas.ilyasapps.drywallestimator)
1. Introduction
This Privacy Policy explains how Drywall Estimator ("the app", "we", "us") handles your information. Drywall Estimator is an offline drywall takeoff, quoting, and job-management tool for drywall contractors. We do not operate any server, we do not maintain user accounts, and your job data never leaves your device unless you choose to share it. Please read this policy before using the app.
2. Information We Collect
2.1 Information You Provide (stored only on your device)
All of the following is entered by you and stored locally in an on-device database. It is not transmitted to us or to any third party:
- Business profile — your business name, phone/email, license number, and insurance number
(used to brand your quotes and invoices).
- Customers — names, phone numbers, email addresses, and addresses you add.
- Jobs & estimates — job details, room dimensions, drywall takeoff parameters (sheet type,
waste factor, finish level, hours per sheet), quotes, and estimate status.
- Materials, invoices, and payments — line items, prices, amounts, and payment records.
- Photos — job photos you capture with your camera or select from your gallery, stored in the
app's private storage.
- Preferences — theme and app settings.
2.2 Information Collected Automatically
- Advertising identifier & ad interaction data — collected by Google AdMob to serve and
measure ads (see Section 4). This may include your device's advertising ID and approximate (coarse, network-based) location.
- Purchase status — Google Play Billing reports whether the one-time premium unlock has been
purchased. We do not receive your payment card details.
We do not collect analytics, we do not use Firebase, and we do not track your behavior across other apps.
3. How We Use Information
- To calculate drywall takeoffs and generate quotes, invoices, and reports on your device.
- To brand your PDF quotes and invoices with your business details, license, and insurance number.
- To display advertising to non-premium users and to determine whether ads should be shown.
- To process and restore your one-time premium purchase.
- To send local reminders about your jobs (on-device notifications only).
Your customer and job data is used solely to provide the app's features. It is never sold, and we never see it.
4. Third-Party Services
The app includes the following Google SDKs. Their handling of data is governed by their own privacy policies:
| Service | Purpose | Data Involved | Policy |
|---|---|---|---|
| Google AdMob | Display banner and rewarded ads | Advertising ID, ad interactions, approximate location, device info | https://policies.google.com/privacy |
| Google UMP (User Messaging Platform) | Ad-consent management (GDPR/consent) | Consent preferences | https://policies.google.com/privacy |
| Google Play Billing | Process the one-time premium purchase | Purchase status | https://policies.google.com/privacy |
Under the EU/EEA/UK, the app presents a Google UMP consent form to obtain your choices for personalized advertising before ads are personalized.
The app does not use Firebase, Google Sign-In, cloud storage, or any analytics SDK.
5. Permissions
| Permission | Why It Is Used |
|---|---|
| INTERNET | Required to load ads and check for app updates. |
| ACCESS_NETWORK_STATE | Detect connectivity for ad loading. |
| POST_NOTIFICATIONS | Show local reminders for your jobs (Android 13+ asks your consent). |
| RECEIVE_BOOT_COMPLETED | Re-schedule your job reminders after the device restarts. |
| FOREGROUND_SERVICE / FOREGROUND_SERVICE_DATA_SYNC | Run the on-device job timer while you track time on a job. |
The app does not request the camera permission at the system level — photo capture is handled by your device's own camera app. The app does not request precise (GPS) location.
6. Data Storage & Security
- All job, customer, financial, and photo data is stored locally on your device (an on-device
Room database and the app's private file storage).
- We do not upload, back up, or sync your data to any cloud server operated by us.
- Because data is stored on your device, it is protected by your device's own security (lock
screen, encryption). If you share a quote or export a CSV file, that file is handled by the app or service you choose to share it with.
- Uninstalling the app removes its locally stored data.
7. Data Sharing
- We do not sell, rent, or share your personal or business data with anyone.
- Data leaves your device only when you choose to share it — for example, sending a PDF quote
via WhatsApp or email, or exporting a CSV file — using your device's standard share sheet.
- The third-party advertising and billing SDKs listed in Section 4 receive only the limited data
described there.
8. Children's Privacy
Drywall Estimator is a professional tool intended for adults and is not directed at children under
- We do not knowingly collect information from children.
9. Your Rights & Choices
- Access & deletion: All your data lives on your device. You can edit or delete customers,
jobs, invoices, and photos within the app, or remove everything by uninstalling the app.
- Advertising: You can reset your advertising ID or opt out of ad personalization in your
device settings, and adjust consent via the app's consent options where applicable.
- Remove ads: Purchasing the one-time premium unlock removes ads.
- Depending on your region (e.g., GDPR/EEA, CCPA/California), you may have additional rights
regarding personal data. Since we do not hold your data on any server, most such requests are satisfied directly on your device; for questions, contact us.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Effective Date" above and posting the revised policy at the hosted URL.
11. Data Retention
We keep your information only for as long as it is needed for the purposes described in this policy.
- All of your entries stay on your device. We operate no server for this data and never receive a copy of it, so there is nothing for us to retain. Your data is kept until you delete the individual entry, clear the app's storage, or uninstall the App. Uninstalling removes all of it from the device.
- Support emails — if you contact us, your message is retained for up to 24 months after your enquiry is resolved, then deleted.
- Purchase records — retained by Google Play for the period required by applicable tax and accounting law. We do not hold separate copies.
12. Data Deletion — How to Delete Your Data
You can delete your data at any time. Delete individual entries Open any entry in the App and tap Delete. It is removed immediately from the device. Uninstall Uninstalling the App removes all locally stored data from your device. Request deletion by email If you cannot access the App, or you want written confirmation that your data has been erased, email us at muhammadilyas15@gmail.com with the subject line "Drywall Estimator – Data Deletion Request". We will verify the request, delete all associated data, and confirm by email within 30 days. There is no charge for this.
