How are cookies and tracking technologies used?
404dn uses cookies and similar technologies on its website. Cookies are small text files stored in your browser that help improve the functionality of the site.
Cookie Type
- Essential Cookies: Used for login sessions, security tokens, and core platform functionality. Disabling these will prevent the site from working properly.
- Functional Cookies: To remember your language preference, theme settings, and previous session data — so you don't have to reconfigure your settings every time you log in.
- Analytics Cookies: To understand which sections are used most frequently. This data is analyzed in aggregate and cannot be used to identify individuals.
You can manage or delete cookies through your browser settings. However, disabling essential cookies will prevent you from logging into your account or completing transactions.
Data Retention & Security Measures
Encryption
Industry-standard encryption is applied to protect your data during storage and transmission. All website connections are maintained through secure protocols at all times.
Retention Period
Account information is retained for as long as your account remains active. Upon closure, data is deleted after a set period in accordance with legal requirements. Financial transaction records are kept as directed by the relevant regulatory authority.
Access Control
Only authorized personnel may access your data, and only to the extent required for their specific role. All access is logged and audited on a regular basis.
Data Sharing with Third Parties
404dn never sells your personal data. However, limited data sharing with trusted partners may occur where necessary to deliver our services:
- Payment Processor: Local payment gateways including bKash and Nagad — only the information strictly necessary to complete a transaction is collected.
- Identity Verification Service: Authorized institutions for account verification — used solely during the verification process.
- Legal Authorities: Information may be disclosed to relevant authorities if required by a court order or legal obligation.
Outside of the cases listed above, your information is never shared with any third party without your consent. Each partner is contractually bound to keep your data confidential.
User Rights
Every 404dn user has the following rights regarding their personal information:
You can view your stored information at any time by logging into your account.
You can contact support to correct any inaccurate or outdated information.
If you request account closure, your data will be deleted except where retention is required by legal obligation.
How will you be notified if the policy changes?
404dn may update this Privacy Policy from time to time. Changes may occur due to service improvements, the addition of new features, or legal requirements.
For significant changes, you will be notified in advance via your registered mobile number or email. Continued use of the platform after any changes will be considered acceptance of the updated policy.
