About this policy
In short: we collect only what we need to give you access, take payments and keep the Service fair. Your chat history is stored in your own browser, not on our servers. Your prompts are sent to AI providers only so they can produce your answers. We never sell your personal data.
This Privacy Policy explains how Dr. Hossain Academy, owned by Dr. M. Z. Hossain ("we", "us" or "our"), handles personal information when you use All AI Zone at allaizone.com and its installable web app (the "Service"). It should be read together with our Terms of Service.
Information we collect
Information you give us
- Email address, when you buy a plan or ask for help, so we can send your access key, receipts and service notices.
- Payment details for manual payments: for bKash or Nagad, the sending mobile number and the transaction ID you enter, so we can match and confirm your payment.
- Messages you send to support, including any information you choose to include.
Information from payment providers
- When you pay by card through Stripe or through SSLCommerz, those providers process your card, bank or mobile banking details. We do not receive or store your full card number. We receive a payment confirmation with details such as your email address, the plan, the amount, the currency, the date, and transaction or subscription identifiers.
Information created when you use the Service
- Your access key and plan, its start and end dates, and its status.
- Usage counts, such as how many credits, comparisons, images, videos, presentations, websites and research reports you have used this period, so we can apply plan allowances.
- Limited technical data, such as IP addresses and request times, used briefly for rate limiting, fraud prevention and security, and the standard logs kept by our hosting provider.
What stays on your device
Your chats, projects, library items, saved settings, language and theme choice are stored in your browser's local storage on your own device. We do not keep a copy of your chat history on our servers. If you clear your browser data or change device, that history may be lost.
How your prompts are handled
To produce an answer, image, video, presentation, website or research report, the text, files and settings you submit for that request are sent through our servers to the AI provider that runs the model you chose (or the models used by features such as Compare and Deep Research). Our servers pass the request on and return the result; they do not store the content of your prompts or of the AI output.
AI providers process your request under their own terms and privacy policies. Some providers may keep request data for a limited time, for example to detect abuse. Please do not include passwords, payment card numbers, national ID numbers or other highly sensitive information in your prompts.
How we use information
- to create, deliver, renew and verify your access key and plan;
- to process payments, confirm manual payments and handle payment errors and disputes;
- to apply plan allowances, credit costs and fair-use limits;
- to send transactional emails, such as your access key, receipts and important notices about the Service;
- to answer support requests;
- to protect the Service and its users from fraud, abuse, key sharing and security threats; and
- to meet legal, tax and accounting obligations.
We do not use your personal data for advertising, and we do not send marketing emails without your consent.
Service providers we use
We rely on trusted companies that process information on our behalf, or as independent providers, only as needed to run the Service:
| Provider | Purpose |
|---|---|
| OpenRouter and the AI model providers it connects to (for example OpenAI, Anthropic, Google, Meta, xAI, DeepSeek, Mistral and others) | Running AI models for chat, comparison, web search, research, presentations and websites |
| fal.ai | Generating images and videos |
| Stripe | International card payments and subscriptions |
| SSLCommerz | Payments in Bangladesh by card, mobile banking and internet banking |
| Resend | Sending emails such as access keys and receipts |
| Netlify | Hosting the website, running our server functions and storing access key, payment and usage records |
Payments made by bKash or Nagad are handled by those wallet providers under their own terms. Some of these providers are located outside your country, including in the United States, so your information may be processed in other countries. Where required, we rely on the safeguards these providers offer for international transfers.
We do not sell your data
We do not sell, rent or trade your personal information, and we do not share it for cross-context behavioural advertising. We share information only with the service providers described above, when the law requires it, to protect our rights or the safety of others, or as part of a transfer of the Service to a new owner who agrees to keep to this policy.
How long we keep information
- Access key, plan and usage records: while the key is active and for up to 24 months afterwards, so we can handle renewals, support requests and disputes.
- Payment records and transaction IDs: for as long as tax, accounting and anti-fraud laws require, normally up to 7 years.
- Rate-limiting and security data: for a short time, usually a few days.
- Support emails: for up to 24 months after the conversation ends.
When information is no longer needed, we delete it or make it anonymous.
Your rights and choices
Depending on where you live, you may have the right to ask for a copy of the personal information we hold about you, to correct it, to delete it, to object to or restrict certain uses, and to receive it in a portable format. You can also withdraw any consent you have given. To make a request, email support@allaizone.com from the email address linked to your plan. We may need to verify your identity before acting, and we will reply within the time the law requires, normally within 30 days.
You can delete the chats and other data stored on your device at any time by clearing them in the app or clearing your browser's site data. You also have the right to complain to a data protection authority where you live.
Cookies and local storage
The Service does not use advertising or tracking cookies. We use your browser's local storage, and a service worker cache for the installable app, to remember your access key, language, theme, chats and projects, and to load the app quickly and show a page when you are offline. Our payment providers may set their own cookies on their checkout pages for security and fraud prevention. Web fonts are loaded from Google Fonts and some app libraries from Cloudflare's cdnjs service, which receive your IP address as part of delivering those files.
Security
We use encrypted connections (HTTPS), restricted access to our records and reputable providers to protect your information. No online service can be completely secure, so please keep your access key private and tell us at once if you think it has been exposed.
Children
The Service is not intended for children under 13, and we do not knowingly collect personal information from them. Users between 13 and 18 should use the Service only with a parent's or guardian's permission. If you believe a child under 13 has given us personal information, please contact us and we will delete it.
Changes to this policy
We may update this Privacy Policy from time to time. The "Last updated" date above shows when it last changed. If we make significant changes, we will give notice on our website or by email.
