Telegram Bot GDPR Data Retention Compliance Guide: Customer Service Session Storage Period, Export and Deletion Request Processing SOP

As a cross-border operations team, are you aware that when a user sends a message through your Telegram Bot, the message along with its attached user ID, IP address, and even browser fingerprint are all personal data under GDPR jurisdiction? Many teams focus only on functionality when using Bots for customer service, overlooking the potential “minefield” of data retention compliance. Mishandling this can lead to fines of up to 20 million euros or 4% of global annual turnover, and severely damage user trust.

This article will break down the Telegram Bot GDPR retention requirements in the context of Telegram Bot customer service, and provide a standard operating procedure (SOP) from retention period setting to handling user data export/deletion requests, helping you achieve compliant operations using tools like TG-Staff.

Why Telegram Bot Customer Service Needs to Pay Attention to GDPR Data Retention?

One of the core principles of GDPR is “Data Minimisation” and “Storage Limitation”. This means that once the purpose for which you collect and process user data is fulfilled (e.g., the customer service inquiry is concluded), you should not retain that data indefinitely.

In your Telegram Bot customer service system, the following types of data fall under GDPR’s definition of “personal data”:

• User Identifiers: Telegram User ID, username, phone number (if provided).
• Session Content: Complete chat records between the user and agents.
• Technical Data: IP addresses, browser fingerprints, URL parameters, device information captured via routing links.
• User Profiles: Descriptions of user attributes formed through tags, notes, etc.

Common Misconception: Many teams think “the Bot is automated, I don’t store user data.” In reality, as long as you use a customer service platform like TG-Staff to record and view sessions, this data is already “processed” and “stored.” Your team is responsible for the security and retention period of this data.

GDPR Requirements for Retention Period of Customer Service Session Data

GDPR does not prescribe a uniform “retention days” but requires you to set a reasonable retention period based on the “processing purpose.” Below are retention recommendations for different data types:

Data Type	Recommended Retention Period	Explanation
Session Messages & User Profiles	6 – 12 months	The purpose of customer service inquiries is usually completed within this period. Beyond this, archive or anonymize.
Routing Link Tracking Data	No more than 30 days	After attribution analysis is complete, tracking data like IP and browser fingerprints should be immediately cleaned or anonymized.
User Profiles (Tags/Notes)	Delete immediately after service relationship ends	When a user explicitly stops using your service or makes a deletion request, process immediately.
Financial/Transaction Records	According to local law (usually 5–10 years)	Such data is not handled within the customer service system, but the legal basis for retention must be clearly communicated to users.

Retention Recommendations for Session Messages and User Profiles

For customer service systems, session data is a core asset. It is recommended to retain raw session data for no more than 12 months. 12 months is sufficient to cover most post-sales, dispute resolution, and operational analysis needs. Historical sessions older than one year have sharply diminished reference value but carry ongoing storage risks.

For user profiles (e.g., tags and notes added via TG-Staff), once the service relationship with the user ends (e.g., the user no longer uses your Bot or explicitly states they no longer need service), delete or anonymize immediately. Retaining profile data of “churned users” not only fails to benefit business but increases compliance burden.

Retention Considerations for Routing Links and Tracking Data

If you use TG-Staff’s routing links for ad attribution, special attention is needed. These links capture the user’s IP, browser information, and URL parameters before the user jumps to the Bot. Under GDPR, such tracking data must be collected with user informed consent (usually communicated via a privacy policy) and should not be retained long-term.

Best Practice: After attribution analysis is complete (e.g., ad attribution window is typically 7–30 days), immediately clean up these access logs via scripts or manual methods. The routing link data management features within the TG-Staff console can help you track and clean up these records.

How to Set Data Retention Policy for Telegram Bot Customer Service System (Using TG-Staff as an Example)

Since TG-Staff currently does not provide automatic expiration deletion, you need to ensure compliance through manual archiving and periodic cleanup. Below is an actionable SOP:

1. Create a Data Classification Inventory: Identify what data is stored in your TG-Staff project (sessions, profiles, routing link logs).
2. Set Cleanup Schedule: For example, set the first Friday of each quarter as “Data Cleanup Day.”
3. Use TG-Staff’s Filtering and Batch Operations: In the console’s “Sessions” list page, use time filters (e.g., “created before 2023-01-01”) to filter sessions older than 12 months.
4. Export and Archive: Before deletion, export session records that need to be retained as CSV or JSON files, and encrypt them for storage locally or in secure cloud storage (e.g., AWS S3 Glacier archive).
5. Execute Deletion: In the TG-Staff console, manually delete or archive these sessions. For user profile data, clear tags and notes directly on the user profile page.

SOP for Handling User Data Export Requests (Right of Access)

When a user requests to view the data you have collected about them, you must comply with the GDPR’s Right of Access. Below is the operational procedure based on TG-Staff:

Step 1: Verify User Identity and Request Scope

• Verify Identity: Confirm the user’s User ID or username through their chat history with your bot on Telegram. Do not act based solely on a message from an unfamiliar account to prevent data leaks.
• Clarify Scope: Ask the user which time period’s data they wish to export, and whether it includes only chat records or also user profiles,分流 link logs, etc. Document the scope.

Step 2: Export Data from the Customer Service System

• Search in TG-Staff: Go to the “User Profile” or “Session Records” page, and find the user by searching with their User ID or username.
• Filter and Extract: Filter all relevant sessions based on the time range determined in Step 1. TG-Staff’s search and filter features can help you quickly locate the data.
• Format Output: Organize the data into a common format. For session records, JSON format is most machine-readable; for simple user profiles and tags, CSV format is more intuitive. You need to manually copy or use TG-Staff’s export function (if available) to obtain the raw data, then organize it yourself.

Step 3: Secure Delivery and Record Keeping

• Secure Delivery: Do not send files containing all personal data directly in Telegram chats. It is recommended to use encrypted email or end-to-end encrypted chat tools like Signal. You can inform the user in Telegram: “Data has been sent via encrypted email to the email address you provided.”
• Record Keeping: Keep an internal log recording: request date, user ID, request scope, data delivery date, and delivery method. This record serves as evidence for regulatory audits and should be retained for 3 years.

SOP for Handling User Deletion Requests (Right to Erasure / Right to be Forgotten)

When a user requests to be forgotten, you must execute the Right to Erasure. The procedure is as follows:

1. Verify Identity: Same as Step 1 of the export request.
2. Locate and Delete Data: In the TG-Staff console, locate all data related to the user:
   • Session Records: Delete or archive all sessions with the user.
   • User Profile: Clear all tags, notes, and custom fields.
   • 分流 Link Logs: In the分流 link management page, find and delete the user’s access records.
3. Confirm Deletion: Verify in the system that the data is no longer accessible through normal paths.
4. Inform the User: Send a message via the Telegram bot confirming that their personal data has been deleted. Also inform the user if any data cannot be deleted due to legal obligations (e.g., financial records), specifying the legal basis for retention and the estimated retention period.

How to Reduce Data Leak Risks with Content Moderation (Pro Feature)

Data leakage is a major risk in GDPR compliance. A common scenario is an agent accidentally sending sensitive information—such as internal wallet addresses or customer ID numbers—into a public chat when replying to a user. Once such a leak occurs, you must report it to the regulatory authority within 72 hours and may face heavy fines.

TG-Staff Pro’s content moderation feature can intercept messages before they are sent, effectively reducing this risk. You can configure it as follows:

1. Create Risk Phrases: In the content moderation module of TG-Staff console, create phrases like “Sensitive Personal Information” or “Internal Wallet Address.”
2. Configure Keywords: Add ID number patterns, specific TRC20/ERC20 wallet addresses or address fragments to the phrase.
3. Set Trigger Actions: Choose “Block Sending” or “Popup for Confirmation.”
4. Associate with Project: Link the risk phrase to the bot project that needs strict control.

This way, if an agent accidentally pastes a wallet address, the system will directly block it and generate an audit record. This is not only an internal control measure but also a direct manifestation of the “data security and accountability” principle in GDPR compliance.

FAQ

Q: How long can GDPR require customer service conversation data be retained? A: GDPR does not specify a fixed number of days; instead, it requires that data retention does not exceed the time necessary to fulfill the purpose of processing. For customer service scenarios, it is generally recommended to retain raw conversation data for 6–12 months, and to delete or anonymize user profile data promptly after the service relationship ends. The specific period should be confirmed based on your business nature and legal counsel.

Q: If a user requests deletion of chat records, how do I handle it in TG-Staff? A: Currently, TG-Staff console provides session management and user profile viewing. To handle deletion requests, you can locate the user’s conversation records in the console and manually delete or archive the relevant messages. For batch processing, it is recommended to contact @tgstaff_robot for more efficient solutions.

Q: If a user requests export of my bot chat records, does TG-Staff support one-click export? A: TG-Staff offers user profile and session search functions. You can filter to find all conversation records of that user. For export, it is recommended to manually copy or extract data via API (if available), organize it into CSV or JSON format, and deliver it to the user. For specific export support, please refer to the official documentation or contact customer service.

Q: Does the free trial meet the basic GDPR data retention requirements? A: The free trial provides basic customer service session functions for testing purposes. However, for formal compliance operations, it is recommended to upgrade to Standard or Pro versions to obtain more comprehensive session management, user profiles, and content moderation features, enabling categorized data storage and compliant processing.

Q: If users access my bot via a referral link, do I need to comply with GDPR for the IP and browser information I collect? A: Yes. IP addresses, browser fingerprints, URL parameters, etc., captured by referral links are personal data and are subject to GDPR. You must clearly inform users in your privacy policy about the purpose and retention period of this data collection and set up reasonable automatic cleanup mechanisms. TG-Staff’s referral link feature supports tracking attribution; it is recommended to use it in conjunction with a privacy statement.
