Privacy Policy

1. About this policy

This policy explains what personal information Dialdao collects, why, who we share it with, and the choices you have. It applies to dialdao.com, the Dialdao apps and our related services, for everyone: people searching, reviewers and business owners.

Dialdao is based at 805/A, CDA Avenue, GEC, Chattogram 4225, Bangladesh, and is responsible for the personal information described here. We follow the data protection laws of Bangladesh.

This policy works together with our Terms of Service. We do not sell your personal information.

2. Information we collect

We collect only what we need to run Dialdao. What we collect depends on how you use it.

3. How we use information

• To run Dialdao: show search results, create and secure accounts, send OTP codes, and connect you with businesses.
• To protect honest reviews: detect fake reviews, duplicate accounts and fraud, and investigate reports.
• To verify businesses: check documents before showing the DD Verified Seal.
• To process payments: confirm Premium payments, send receipts and handle refunds.
• To improve Dialdao: understand which searches and features work, and fix problems.
• To communicate: send service messages, and marketing messages only if you haven't opted out.
• To follow the law: keep records we are legally required to keep, and respond to lawful requests.

We ask for your consent where the law requires it, for example when you sign up, upload identity documents, allow location access, or accept analytics cookies. You can withdraw consent at any time (section 11), though some features may then stop working.

4. What is public on Dialdao

Some information is meant to be seen by everyone:

• Reviews and ratings you post, shown with your display name and profile photo. You can choose a display name that isn't your full name.
• Business listings: business name, address, phone, hours, photos, prices, offers, and owners' replies to reviews.

Never public: your mobile number, email, identity documents, payment details, and the enquiries you send to businesses. Search engines may show public pages, and others may copy public content, so think before you post.

5. Who we share information with

Our service providers may use your information only to provide their service to us, and must keep it secure. We never share identity documents with other businesses or users, and we never sell personal information.

6. Identity documents

NID and trade license copies are the most sensitive information we hold, so we treat them differently.

• One purpose only. We use them only to verify a business and its owner, prevent fraud, and meet legal obligations. Never for marketing.
• Limited access. Only trained verification staff can view them, and every access is logged.
• Never public. The Seal shows that documents were checked. The documents themselves, and your NID number, are never shown to anyone else.
• Kept only as long as needed. See section 10.

By uploading a document, you consent to this use and confirm the document is genuine and belongs to you or your business.

7. Teens under 18

Anyone can browse Dialdao. To create an account, you must be at least 13. Users aged 13 to 17 need permission from a parent or guardian.

For users under 18, we:

• collect only what's needed to run their account;
• don't show them personalised advertising, or send marketing messages;
• don't let them claim a business, upload identity documents or make payments.

We don't knowingly collect information from children under 13. If you believe a child under 13, or a teen without permission, has an account, email support@dialdao.com and we will delete it. A parent or guardian can also ask us to see, correct or delete their teen's information.

8. Cookies, analytics and advertising

Cookies are small files saved by your browser. We use three kinds:

Analytics and advertising cookies load only after you accept them in our cookie banner. You can change your choice at any time from the "Cookie settings" link at the bottom of every page, or by clearing cookies in your browser. In our app, similar tools are controlled from settings.

9. Where data is stored and how it is protected

Where. Dialdao uses cloud service providers, and some of their servers are outside Bangladesh, for example in the United States. When information is stored abroad, we choose providers with strong security, and we follow Bangladeshi law on transferring and storing personal data, including any requirement to keep certain data inside Bangladesh.

How we protect it.

• encrypted connections (HTTPS) for everything you send us;
• encrypted storage for identity documents;
• access limited to staff who need it, with access logged;
• OTP login, so no passwords are stored.

No system is completely secure. If a breach puts your information at risk, we will tell you and the relevant authority as the law requires, and explain what we're doing about it.

10. How long we keep information

We may keep information longer if the law requires it, or to resolve a dispute.

11. Your choices and rights

You can ask us to:

• see the personal information we hold about you, and get a copy;
• correct information that is wrong or out of date;
• delete your account and personal information, except what the law requires us to keep;
• withdraw consent, for example for location, cookies or marketing;
• stop marketing by replying STOP to any marketing message, or from your settings.

If your personal details appear in a listing. Unclaimed listings are built from public information. If one shows your personal name, mobile number or home address without your permission, ask us to remove it, and we will review it within 7 working days.

How to ask. Most things can be done in your account settings. Otherwise, email support@dialdao.com and include the mobile number on your account. We may confirm your identity first, then reply within 30 days. If you're unhappy with our answer, you can complain to Bangladesh's data protection authority.

12. Changes to this policy and contact

When we make material changes, we tell account holders at least 15 days in advance by app notification, SMS or email, and update the date at the top. If a change needs your consent under the law, we will ask for it.
