Terms of Service

MOMU AI · Last updated: October 20, 2026

Welcome to MOMU AI (“MOMU”, “we”, “us”, “our”). MOMU is an AI chat assistant that answers questions in Bangla, Banglish and English, does exact maths, can look things up on the web, shows the weather, reads files and pictures you attach, and can remember things you ask it to. MOMU is created and run by Muntasir. These Terms are the agreement between you and us about using MOMU. Please read them. If you do not agree, please do not create an account or use MOMU.

1.Accepting these Terms

By creating an account, signing in (including with Google), or using MOMU, you confirm that you have read and accept these Terms and our Privacy Policy. On the sign-up page, clicking the button to create your account means you accept both.

2.Who can use MOMU

• You must be old enough to use MOMU where you live. That is 8 years old where no local law asks for more, and older in places whose laws set a higher age for online services (for example 13 in the United States and the United Kingdom, and up to 16 in some European countries). When you sign up we ask for your date of birth and country or region to check this. If you are under 18, you should use MOMU only with the permission and supervision of a parent or guardian.
• You must give a real email address that you control, and keep it up to date.
• If we closed or suspended your account, you may not open another one to get around that.

3.Your account

• You are responsible for your password, your email account and everything done through your MOMU account. Keep them private and use a password that is not used elsewhere.
• You can be signed in on a limited number of devices at once. When the limit is reached, the oldest sessions may be signed out. You can see and sign out your devices in Settings.
• Tell us straight away through Support if you think someone else is using your account.
• One person, one account. Do not sell, share or transfer your account.

4.What MOMU is (and isn’t)

MOMU uses artificial intelligence, built-in rules, calculators, its own learned knowledge, and outside services to answer you. AI can be wrong. It can misunderstand, leave things out, sound sure when it is not, or repeat mistakes found in its sources.

• MOMU’s answers are for general information, learning and everyday help. They are not professional medical, legal, financial, safety, emergency or mental-health advice. For those, talk to a qualified person. In an emergency, contact your local emergency services.
• Always check important facts, numbers, weather warnings, dates, quotes and sources yourself before you rely on them or act on them.
• Weather, time and web information comes from outside services and may be late, incomplete or wrong.
• You are responsible for how you use what MOMU gives you.

5.Acceptable use

When you use MOMU you agree not to:

• Break any law, or help someone else break a law.
• Create, ask for or share sexual content involving children, or any content that exploits or endangers a child.
• Threaten, harass, bully, stalk, scam, defame or impersonate anyone, or promote hatred or violence.
• Ask for help to make weapons, to hurt yourself or others, or to commit fraud, identity theft or hacking.
• Upload files, pictures or text that you have no right to use, that contain malware, or that contain other people’s private information without a good reason.
• Try to break, probe, overload, scrape, reverse-engineer or get around the limits, security, sign-in, rate limits or safety rules of MOMU, or try to get at other people’s accounts or data.
• Try to make MOMU reveal its hidden instructions, keys, passwords, internal settings or the technical details of the services behind it.
• Use MOMU to send spam, or use automated tools (bots) to use it in bulk without our written permission.
• Present MOMU’s answers as human work in a way that deceives people, or use them in a way that causes harm.

We may refuse a request, remove content, limit features or close an account that breaks these rules.

6.Your content

• You own your content — your messages, files, pictures and anything else you put into MOMU (“Your Content”). You are responsible for it and promise you have the right to use it.
• You give us a limited, worldwide, non-exclusive, royalty-free permission to store, process, copy and display Your Content, and to send it to the outside services described in the Privacy Policy, only so we can run MOMU for you, keep it safe, fix problems, and — as explained in the Privacy Policy — help MOMU learn and improve.
• Answers MOMU produces for you are provided to you for your own use. Because AI can give similar answers to different people, we cannot promise answers are unique or free of other people’s rights.
• If you give us feedback or ideas, we may use them without owing you anything.

7.Sharing, memory and incognito

• Shared links. If you share a chat, a message or a project, anyone who has the link can view it. Only share what you are happy for others to see. You can see and delete your shared links in Settings; deleting a link stops others opening it but does not delete your original chat.
• Memory and “Your Info”. MOMU can remember things you ask it to remember and use the profile information you add (for example what you do, or more about you) to make answers more personal. You can view, edit or delete these in Settings. You decide what to tell MOMU, so please do not store things like passwords or card numbers there.
• Incognito chats. An incognito chat is not saved to your chat history and does not use your saved memory or profile information. It is not a promise of total secrecy: your messages are still processed by MOMU and the outside services needed to answer them, and — as the incognito screen and the Privacy Policy explain — a question and answer may be kept without your name for training.

8.Web search and third-party services

MOMU relies on other companies’ services (for example AI model providers, web search and weather information, speech recognition, Google sign-in, email delivery, and hosting). We do not control them, they may change or stop, and their own terms may apply when you use features that depend on them. Links to other websites in answers or sources are provided for convenience; we are not responsible for those websites.

9.Support

You can contact us through the Support page. Support answers are by email. Please do not send passwords, card numbers or very private information in a support request. We may keep a record of requests and replies to help you and to improve MOMU. We cannot promise a reply time, except where MOMU states one itself (for example the automatic 24-hour steps for reopening or fully deleting an account).

10.Deleting your account

• You can delete your account in Settings. You will be signed out everywhere straight away.
• For 30 days afterwards the account cannot be used to log in and the same email cannot be used for a new account. During this time you can send a Support request to reopen the account if you change your mind, or to delete it completely sooner so you can sign up again with the same email.
• After 30 days your account and data are deleted for good and cannot be recovered, except for a limited set of information we may need to keep longer where the law requires it, to prevent abuse, or to resolve disputes. See the Privacy Policy.

11.Suspension and ending access

We may warn you, limit features, suspend or close your account — with or without notice — if you break these Terms or the law, if your use puts MOMU, other people or us at risk, if your account looks hacked or abused, or if we must by law. We may also stop offering MOMU, or part of it, at any time. You can stop using MOMU at any time.

12.Availability and changes to MOMU

MOMU is provided as it is and may be unavailable at times — for example during maintenance, updates, outages of outside services, or usage limits. We may change, add, limit or remove features, the AI models behind MOMU, and usage limits (such as the number or size of files, messages or support requests) at any time. We do not promise that MOMU will always work, be fast, be error-free, or keep any particular feature.

13.Copyright and our rights

• What belongs to us. MOMU — its name, logo, look and feel, software, written content, help articles, and the knowledge MOMU has learned — belongs to us or our licensors. These Terms give you no ownership of it. You may only use MOMU in the ways allowed here.
• What you may not do. Do not copy, modify, reproduce, resell, publicly display, scrape or distribute any part of MOMU, and do not build a competing service from MOMU’s code, design, data or answers in bulk. Do not remove or hide any copyright or ownership notice. Do not use the MOMU name or logo without our written permission.
• What stays yours. Your Content remains yours (see section 6). Nothing here takes your ownership away from it.
• Third-party material. Other companies’ names, logos, websites and content that appear in answers or sources belong to their owners. They are shown for information and are not owned or endorsed by us.
• Personal use of answers. You may use MOMU’s answers for your own purposes. You are responsible for checking that what you do with them does not break anyone else’s rights.

14.Copyright complaints

We respect other people’s creative work and ask you to do the same. If you believe content in MOMU — for example a shared link, a shared project, or a file someone uploaded — copies your work without permission, contact us through the Support page and choose “Talk to our team”. Please include:

• A description of your work and, if you can, where it can be seen.
• The link or exact place in MOMU where the content appears.
• Your name and the email address we can reply to.
• A statement that you are the owner, or are allowed to act for the owner, and that you believe the use is not authorised.

We may remove or disable the content, tell the person who posted it, and close the account of anyone who repeatedly breaks other people’s copyright. Please send only complaints you believe are true — a false claim can have legal consequences.

15.Disclaimers

To the fullest extent the law allows, MOMU and everything in it are provided “as is” and “as available”, without any promise (express or implied) of accuracy, completeness, reliability, fitness for a particular purpose, or that it will not infringe anyone’s rights. We do not promise that MOMU will meet your needs or that your content will never be lost, so please keep your own copy of anything important (Settings lets you export your chats).

16.Limit of liability

To the fullest extent the law allows, we (and the people who run or help run MOMU) are not responsible for any indirect, incidental, special, consequential or punitive loss, or for loss of data, profit, income, opportunity or goodwill, or for any decision you make or action you take because of an AI answer. Where the law does not allow a limit, our total responsibility to you for any claim about MOMU will not be more than what you paid us for MOMU in the 12 months before the claim (and if MOMU is free for you, that is zero). Nothing in these Terms limits anything that cannot be limited by law.

17.Changes to these Terms

We may update these Terms from time to time. When we do, we will change the “Last updated” date above, and for important changes we will try to tell you in MOMU or by email. If you keep using MOMU after a change, you accept the new Terms. If you do not agree, stop using MOMU and delete your account.

18.Governing law

These Terms are governed by the laws of Bangladesh, and the courts of Bangladesh are the ones to settle any dispute, unless the law where you live gives you rights that cannot be changed by an agreement like this one. We would always prefer that you contact us first so we can try to sort things out.

Privacy Policy

MOMU AI · Last updated: October 20, 2026

This policy explains what information MOMU AI collects, why, who it is shared with, how long we keep it, and the choices you have. We have tried to write it in plain language. We do not sell your personal information, and MOMU has no advertising.

• 2. Information we collect
• 3. How we use it
• 4. AI, learning and training
• 5. Who we share it with
• 6. Who can see your data
• 7. Your choices

1.Who we are

MOMU AI is created and run by Muntasir. In this policy “MOMU”, “we”, “us” means the people who run MOMU AI. This policy applies to the MOMU website and app and to the Support, sharing and sign-in pages. See also our Terms of Service.

2.Information we collect

Information you give us

• Account details: Your email address, the name MOMU should call you (nickname), and your password (we keep only a scrambled “hash”, never the password itself). Your date of birth and the country or region you live in, which we use to check the minimum age and keep to the law (you can see and change your age in Settings). If you sign in with Google, we receive your email, name and a Google account identifier from Google; we never see your Google password. You can also add a profile picture, and set preferences such as theme and reply language.
• Your chats: The messages you send, the replies MOMU gives, chat titles, projects, and the options you pick (for example Web search or Weather and Time).
• Files and pictures you attach: For documents (PDF, Word, Excel, text and similar) we keep the text MOMU read from it and the original file, so you can preview or download it later. For pictures, we keep the picture with the message. Files you upload but never send are removed after a few hours.
• Voice typing: If you use the microphone to dictate, your device’s own speech recognition is tried first. If that is not available, the recording is sent to a speech-to-text service to turn it into text. We use it only to produce the text; we do not keep your recordings.
• Memory and “Your Info”: Things you ask MOMU to remember, and profile details you choose to add (such as what you do or more about you).
• Location: A city you type, or a location your browser gives us only if you tap “Detect” or allow it. It is saved for your account to give weather and time for your place.
• Support requests and problem reports: Your name (optional), email, device type, category and the message you write, and our replies.
• Shared links: The chats, messages or projects you choose to share.

Information collected automatically

• Device and sign-in details: A device name worked out from your browser (for example “Chrome on Windows”), browser details (user agent), IP address, and when you signed in and were last active. This powers “My devices” and helps protect your account.
• Security and usage records: Verification and reset codes (stored scrambled, and they expire), sign-in attempts and request counts used for rate limits, error logs, and activity records used to run, protect and fix MOMU.

Information from others: web pages, weather data and other results that MOMU fetches to answer you; and, if you use Google sign-in, the details Google sends us.

3.How we use it

We use your information for these reasons:

• To create and run your account, keep you signed in, and give you MOMU’s answers.
• To make answers more personal (your memory, profile info, language, answer length and tone settings) — and to stop doing so when you delete them or use incognito.
• To send you emails you need: verification and reset codes, welcome and account messages, and replies to Support.
• To keep MOMU safe: stop abuse, spam and attacks, enforce our Terms, and investigate problems.
• To fix bugs, measure how features are used, and improve MOMU, including as described in section 4.
• To follow the law and respond to valid legal requests.

4.AI, learning and training

• Outside AI providers. To answer you, the text of your message (and, when needed, recent messages from the same chat, your attached file text or pictures, and your memory or profile info if you or the settings allow it) is sent to third-party AI model providers. They process it to produce the reply. We choose them for this purpose and only send what is needed. We do not name them here because they can change, and they may be added or replaced as MOMU grows.
• MOMU learns. MOMU keeps a knowledge base of facts, and a good question-and-answer pair from conversations may be kept so MOMU can answer similar questions faster next time and so we can train and improve MOMU’s own AI. We work to keep personal details out of what is learned, but please do not type secrets into a chat that you would not want kept.
• Memory is separate. What you ask MOMU to remember about you, and your profile information, are private to your account and are not part of MOMU’s training data.
• Pictures. Pictures are used for training only where the “train on image chats” setting was on when you uploaded them. It is off by default.
• Incognito. Incognito chats are not saved to your history, do not use your memory or profile info, and do not appear in your chat list or in admin activity records. A question-and-answer pair from an incognito chat may still be kept without your name or account for training, never when a file or picture was part of it. The incognito screen tells you this.
• Learned knowledge that has been mixed into MOMU’s general knowledge or training data cannot always be taken out one piece at a time, even after you delete your chat or account — but it is not tied to your identity.
• No person at MOMU makes legal or similarly important decisions about you using only AI output.

5.Who we share it with

We share information only as needed to run MOMU, with:

• AI model providers — to generate answers (section 4).
• Web search, web-page and weather services — a search phrase or place name is sent to find fresh answers when search or weather is used.
• Speech-to-text service — only when your device’s own voice typing is unavailable.
• Google — if you choose “Continue with Google”, to sign you in.
• Email delivery service — to send codes and messages to your email.
• Hosting, database and infrastructure providers — who store and run MOMU for us.
• People you choose — anyone you give a shared link to can see what you shared.
• Authorities or professional advisers — if the law requires it, to protect people’s safety, or to protect our rights.
• A new owner — if MOMU is ever transferred to someone else, your information may move with it, under this policy or a notice to you.

These providers may only use your information to give their service to us, under their own terms and privacy rules. We never sell your information and never share it for advertising.

6.Who can see your data

• You — your chats, memory, files and settings are private to your account.
• MOMU administrators — a small number of administrators can see account information (email, nickname, status, devices), support tickets and problem reports, and activity records of chats that are used to run, protect and improve MOMU. They may look at them to fix problems, answer support, deal with abuse, or stop harm. Incognito chats are not shown there. Administrators do not see your password.
• Others — no one else, unless you share a link or the law requires it.

7.Your choices

• Edit your details: Change your nickname, email (with a code sent to the new address), password, picture, theme, reply language and answer length in Settings.
• Memory and profile info: View, edit, delete a single memory, or delete all and turn memory off, in Settings.
• Chats: Delete one chat or all chats. Deleting a chat removes its messages and attachments from your account.
• Export: Download your chats from Settings.
• Shared links: See and delete every link you shared (Settings → Shared links).
• Devices: See where you are signed in and sign out any device.
• Location: Clear or change your saved city; you can refuse the browser’s location permission.
• Incognito: Use an incognito chat when you do not want a conversation saved to your history.
• Delete your account: In Settings. See section 8.
• Other requests: To ask about, correct or remove information we hold about you, or to object to a use of it, contact us through Support. Depending on where you live, you may have legal rights over your personal information (such as access, correction, deletion, or objecting). We will respond as the law requires.

8.How long we keep data

• Chats, files, pictures, memory and settings: Until you delete them or your account.
• Deleted account: The account is closed at once and you are signed out everywhere. For 30 days we keep it so it can be reopened if you ask Support. After 30 days it is deleted for good and cannot be recovered; the email can then sign up again. You can ask Support to delete it completely sooner.
• Unsent uploads: Removed after a few hours.
• Codes: Expire after a short time and are replaced by newer ones.
• Support tickets and reports: Kept as long as we need them to help you, prevent abuse and keep records.
• Security records: Kept for a limited time.
• Backups and legal reasons: Some data may stay for a short time in backups, and a limited set may be kept longer where the law requires or to prevent fraud and abuse.
• Learned or training data that is not tied to your identity may be kept (see section 4).

9.Cookies and browser storage

MOMU does not use advertising or tracking cookies. It uses your browser’s storage to work properly: to keep you signed in, remember your theme and settings, and keep drafts (unsent text, attachments and chosen options) for each chat so you do not lose them. Drafts stay on your device and are cleared when you log out. You can clear this storage in your browser at any time, but you may be signed out and lose unsent drafts.

10.Security

We use reasonable measures to protect your information, such as encrypted connections (HTTPS), scrambled storage of passwords and codes, sessions that can be signed out from any device, limits on sign-in and request attempts, and restricted access for administrators. Our systems’ passwords, keys and settings are kept private and are never shown to users. No online service is perfectly secure, so we cannot promise absolute security. Please use a strong, unique password and tell us through Support at once if you think your account was misused.

11.Children

MOMU is not for children below the minimum age for the place where they live — 8 where no law sets a higher age, and higher in some countries and regions. We check this when you create an account, using the date of birth and country or region you type, and we do not create an account for someone who is below it. We do not knowingly collect information from children who are too young. If you believe a child who is too young has an account, tell us through Support and we will delete it. People under 18 should have a parent or guardian’s permission.

12.Other countries

MOMU and the services it uses may be located in different countries. Your information may therefore be processed outside the country where you live, where privacy laws may differ. By using MOMU you understand this, and we require our providers to protect it appropriately.

13.Changes to this policy

We may update this policy. We will change the “Last updated” date above and, for important changes, try to tell you in MOMU or by email. Using MOMU after a change means you accept the updated policy.
