This Privacy Policy explains what information Digsil collects, why, how long it is kept and the choices you have. It covers:
- Our Android apps published on Google Play under the Digsil developer account — currently Mentora – AI Math Tutor and Halal Chef — and any future app that links to this page;
- Our WordPress plugins, such as Digsil 404 SEO Guardian;
- This website, www.digsil.com, including the contact and data-request forms.
Our web tools Keyword Checker (kwchecker.com) and Prompt Writer (promptswriter.net) run on their own domains and are covered by the policies published on those sites.
The short version: we do not show ads, we do not sell or share your personal information for advertising, we do not ask you to create an account, and we collect only what a feature needs to work.
1. Who we are
Digsil is the brand of Murad Ali Shah, an independent software developer based in Pakistan. Murad Ali Shah is the "data controller" — the person responsible for your information — for the apps, plugins and website listed above. Contact details are in Section 17.
In this policy "we", "us" and "our" mean Murad Ali Shah trading as Digsil. "You" means anyone who uses our apps, plugins or website.
2. Information we collect
What we collect depends on the app or feature you use. We follow data minimisation: if a feature does not need a piece of information, we do not collect it.
Information you give us
- Text you type into AI features — for example a maths question in Mentora, or a recipe request in Halal Chef — together with the short conversation context the feature needs to answer.
- Photos you choose to take or select — for example a photo of a maths problem, or of a food label to check ingredients. Text is extracted on your device where possible; where an AI feature needs the image or the extracted text, only that content is sent for the request.
- Voice input — turned into text on your device by Android's speech recognition. We never receive or store raw audio.
- Preferences and in-app data — such as dietary choices, saved recipes, meal plans, history and settings. These are stored on your device.
- Messages you send us — by email or through the forms on this website (your name, email address, the app concerned and your message).
Information collected automatically
- Technical data needed to run online features — your IP address, device and operating-system version and app version reach our servers when an app makes a request. We use the IP address briefly to stop abuse (rate limiting) and keep standard server logs for security.
- An anonymous app identifier — Halal Chef creates a random identifier on first launch and uses it to obtain a short-lived access token for its AI service. It is not linked to your name, email or Google account and lets us apply fair-use limits and block abuse.
- Crash and diagnostic reports — Halal Chef uses Firebase Crashlytics (a Google service) to send crash reports: the stack trace, device model, Android version, app version and a Crashlytics installation identifier. Other apps may rely on the crash data that Google Play itself provides to developers.
- Purchase information — if you subscribe, Google Play confirms the purchase to the app (a purchase token and the subscription's status). We never see your card or payment details.
What we do not collect
We do not collect your precise or approximate location, contacts, call logs, SMS, photos you have not chosen, files outside the app, advertising IDs or biometric data. We do not require an account, so we do not hold passwords for our apps.
3. Device permissions
Each permission is requested only when you use the feature that needs it, and you can withdraw it at any time in Android Settings → Apps.
- Camera — to photograph a maths problem or a food label.
- Microphone — for voice input, converted to text on your device.
- Internet and network state — for AI answers, subscription checks and to tell you when you are offline.
- Storage / media access — only to save or share files you create, such as a PDF export or a recipe card.
- Notifications (if offered) — for reminders you switch on.
- Vibration — for haptic feedback.
4. How we use information and our legal bases
| Purpose | Information used | Legal basis (EEA/UK) |
|---|---|---|
| Provide the feature you asked for, such as an AI answer or recipe | Your input, photos or extracted text, conversation context | Performance of our contract with you |
| Keep services secure and fair; prevent spam and abuse | IP address, anonymous app identifier, request counts | Legitimate interests |
| Fix crashes and improve reliability | Crash and diagnostic reports | Legitimate interests |
| Provide and verify subscriptions | Google Play purchase token and status | Performance of contract; legal obligation (records) |
| Answer support, privacy and deletion requests | Your name, email and message | Legitimate interests; legal obligation |
| Use the camera, microphone or notifications | Only the data the feature captures | Your consent (the Android permission), which you can withdraw |
We do not use your information for advertising or profiling, we do not sell it, and we do not use your content to train AI models.
5. AI features
Mentora and Halal Chef include AI features. When you use them:
- Your request travels over an encrypted HTTPS connection to our own backend (for example api.digsil.com or airecipe.digsil.com).
- Our backend sends the request, using our own API keys, to an AI provider — currently OpenAI, Google (Gemini) or Anthropic (Claude), depending on the app and on which provider is available. Your device never talks to the AI provider directly and the provider does not receive your name or email from us.
- The answer is returned to your device. Our servers do not keep the content of your request after the answer has been delivered, apart from short-lived technical logs needed to keep the service running.
We use these providers through their developer APIs and, wherever a provider offers the control, we opt out of our requests being used to train its models. Providers may keep request data for a limited time under their own terms, for example to detect abuse.
Please do not enter sensitive personal information (health, financial or identity details) into AI features. AI answers can be wrong — see our Disclaimer. You can report an offensive, harmful or incorrect AI answer using the in-app feedback or report option where it is available, or by emailing support@digsil.com.
6. Data stored on your device
Most app data — history, saved items, preferences, cached content and your subscription status — stays on your device. Sensitive values such as subscription status are kept in Android's encrypted storage. You can remove this data at any time with the app's "Clear data" option where available, through Android Settings → Apps → [app] → Storage → Clear data, or by uninstalling the app. Android's own backup may copy app data to your Google account if you have backup switched on; that copy is controlled by Google and your device settings.
7. Subscriptions and payments
Paid plans are sold and billed by Google Play. Google processes your payment details under the Google Privacy Policy; we only receive confirmation that a purchase is valid and active. Your subscription is tied to your Google account, so you can restore it on another device signed in to the same account. You can cancel at any time in the Google Play Store app (Profile → Payments & subscriptions → Subscriptions). Refunds follow Google Play's refund policy and your local law — see our Terms of Service.
8. Service providers we use
We share information only with providers that help us run our services, and only what they need:
- Google — Google Play (distribution, billing, subscriptions, crash data), Firebase Crashlytics (crash reports, Halal Chef), ML Kit and Android speech recognition (processed on your device).
- AI providers — OpenAI, Google (Gemini) and Anthropic, for AI answers, as described in Section 5.
- Hosting and network providers — Cloudflare (Halal Chef's AI service runs on Cloudflare Workers), Railway (Mentora's AI backend) and our web host for this website and email.
We may also disclose information if the law requires it, to protect people's safety, or to defend our legal rights. If Digsil or an app is ever transferred to someone else, this policy will continue to apply to the information transferred, and we will tell you before it is used in a materially different way.
9. Our website and WordPress plugins
This website does not use analytics, advertising or tracking cookies, and the fonts are hosted on our own server, so your visit is not shared with font or analytics services. Our web server keeps standard access logs (IP address, date, page requested, browser type) for security. If you use a form, we store your name, email and message so we can reply. See our Cookie Policy.
Digsil 404 SEO Guardian runs entirely inside your own WordPress site. It records which missing URLs were requested, how often and when, so that you can fix them — it does not store visitors' IP addresses or user agents, and it does not send your site's data to us. You remain the controller of any data on your WordPress site.
10. How long we keep information
| Information | How long |
|---|---|
| AI request content on our servers | Not kept after the answer is delivered (only short-lived technical logs) |
| Rate-limit counters and anonymous app identifiers | Rolling windows of minutes to hours for counters; the identifier until you clear app data or uninstall |
| Crash reports (Firebase Crashlytics) | Up to 90 days |
| Web-server security logs | A limited period, after which our host rotates and deletes them |
| Support, privacy and contact messages | Up to 2 years after the conversation ends, or sooner if you ask us to delete them |
| On-device app data | Until you clear it or uninstall the app |
| Purchase records | Kept by Google Play under its own policies; we keep only what tax or accounting law requires |
11. Your rights
Wherever you live, you can ask us to tell you what information we hold about you, correct it, delete it or stop using it. Depending on your location you may also have these rights:
- EEA, UK and Switzerland (GDPR / UK GDPR): access, rectification, erasure, restriction, data portability, objection to processing based on legitimate interests, withdrawal of consent at any time, and the right to complain to your local data-protection authority.
- California and other US states with privacy laws: the right to know, delete and correct personal information, and to opt out of its "sale" or "sharing". We do not sell or share personal information, and we do not use sensitive personal information to infer characteristics about you. We will not treat you differently for exercising your rights.
- Elsewhere: any rights your local law gives you, which we will honour.
To make a request, use the form on our Data Deletion page or email support@digsil.com. Because we do not run accounts, we may ask for details — such as the email you wrote from, or a purchase order number — so that we act on the right data. We reply within 30 days, and within 45 days where US state law allows.
12. Children
Our apps are general-audience learning and productivity tools; they are not directed at children under 13 (or the minimum age in your country) and we do not knowingly collect personal information from them. The apps work without registration and show no advertising. If you are a parent or guardian and think your child has sent us personal information — for example in a support email — contact support@digsil.com and we will delete it. If an app is ever made for children, we will follow Google Play's Families Policy and the US Children's Online Privacy Protection Rule (COPPA), as amended in 2025.
13. Security
All connections between our apps and our servers use HTTPS (TLS). API keys are kept on our servers, never inside the apps. Our backends authenticate requests and rate-limit traffic, sensitive on-device values are encrypted, and access to our servers is limited to the developer. No system is perfectly secure; if a breach affects your rights, we will notify you and the relevant authorities where the law requires.
14. International transfers
We are based in Pakistan, and our providers run servers in other countries, including the United States and the European Union. Where the GDPR or UK GDPR applies, we rely on our providers' approved safeguards — such as the EU Standard Contractual Clauses or, where a provider is certified, the EU–US Data Privacy Framework — and all data is encrypted in transit.
15. Google Play requirements
Each app's Data safety section on Google Play describes the same practices as this policy. Our apps follow the Google Play Developer Program Policies, including the User Data, Permissions, AI-Generated Content and Subscriptions policies. Our developer details — including our trader status for users in the European Economic Area and the United Kingdom — are shown on our Google Play developer page; see our Terms of Service.
16. Changes to this policy
When our apps or the law change, we will update this policy and the "Last updated" date. For significant changes we will also tell you in the app or in the Google Play release notes before the change takes effect. The current version is always at www.digsil.com/privacy-policy.
17. Contact
Questions or requests about privacy: support@digsil.com. We aim to reply within a few working days and always within 30 days.
