Yes, Telegram bots need a privacy policy. Every Telegram bot processes personal data through the Bot API, including user IDs, names, language codes, and message content. Under GDPR and other privacy laws, bot developers must disclose what data they collect, how they use it, and whether they share it with third parties. If your bot handles payments, inline queries, or location data, your disclosure obligations are even greater.
Telegram has become one of the most popular messaging platforms in the world, with over 900 million monthly active users. The Telegram Bot API powers millions of bots that provide everything from news feeds and weather updates to payment processing and customer support automation.
But most Telegram bot developers focus on building features, not on privacy compliance. That is a problem because every interaction with your bot involves personal data. When a user sends a message to your bot, the Bot API delivers their user ID, first name, and potentially their username, last name, and language code. If your bot supports inline queries, location sharing, or payments, even more sensitive data flows through your system.
This guide covers exactly what data Telegram bots access, how the Bot API data flow works, what payment processing means for your privacy obligations, and the fastest way to create a compliant privacy policy for your Telegram bot.
Why Telegram Bots Need a Privacy Policy
Unlike some platforms that explicitly mandate a privacy policy for all bots, Telegram's requirement comes from a combination of legal obligations and platform expectations. Every Telegram bot processes personal data, and under GDPR, CCPA, and other privacy regulations, that processing must be transparent.

Data processed per interaction
Telegram's Terms of Service require developers to comply with all applicable laws when using the Bot API. Since GDPR applies to any service processing EU residents' data, and Telegram has a massive European user base, most public bots are subject to GDPR. The regulation requires a clear and accessible privacy policy that explains what data you process and why.
Beyond legal requirements, having a privacy policy builds trust with your bot's users. Group administrators increasingly review a bot's privacy practices before adding it to their groups. Users who see a /privacy command or a linked privacy policy are more likely to trust your bot with their data and continue using it.
If your bot is listed in third-party bot directories or catalogs, most require or strongly recommend a privacy policy. Bots without one may be deprioritized or removed from listings entirely.
Q: My bot only works in private chats. Do I still need a privacy policy?
Yes. Whether your bot operates in private chats, group chats, or channels does not change the fact that it processes personal data. A bot in private chats still receives user IDs, names, and message content through the Bot API. GDPR obligations apply based on data processing, not the chat context.
Q: Does Telegram review my bot's privacy policy?
Telegram does not currently conduct routine privacy policy reviews for most bots. However, if your bot is reported for privacy violations or if you apply for Telegram's verified badge, your practices may be scrutinized. Having a comprehensive privacy policy from the start protects you in both scenarios.
Data Your Telegram Bot Accesses
Understanding what data your bot receives is essential for writing an accurate privacy policy. The Telegram Bot API delivers different data depending on the type of interaction. Here is a comprehensive breakdown of the data fields your bot can access.
| Data Type | How Bot Receives It | Personal Data? | User Action Required? |
|---|---|---|---|
| User ID | Every update from the Bot API | Yes (unique identifier) | No (automatic) |
| Username | User object in updates (optional field) | Yes (personally identifiable) | No (automatic if set) |
| First / Last name | User object in every update | Yes (personally identifiable) | No (automatic) |
| Language code | User object (IETF language tag) | Potentially (reveals locale) | No (automatic) |
| Chat ID | Every message and update | Yes in private chats (equals user ID) | No (automatic) |
| Messages | Text messages sent to the bot | Yes (user-generated content) | Yes (user sends message) |
| Photos / Documents | File attachments in messages | Yes (may contain personal content) | Yes (user sends file) |
| Location | Location message or live location | Yes (sensitive, reveals position) | Yes (user shares location) |
| Phone number | Contact sharing (request_contact) | Yes (sensitive personal data) | Yes (explicit user consent) |
| Inline queries | InlineQuery updates (query text + user) | Yes (reveals search intent) | Yes (user types inline query) |
The key distinction for your privacy policy is between data that Telegram sends automatically with every update (user ID, first name, chat ID) and data that requires explicit user action (location, phone number, photos). Both types must be disclosed, but data requiring user action can be framed as voluntary sharing in your policy.
Did you know?
Telegram user IDs are permanent numeric identifiers that never change, even if a user changes their username or display name. Under GDPR, these are classified as personal data because they can uniquely identify an individual across interactions. This means every Telegram bot that receives any update is processing personal data, regardless of whether it stores anything in a database.
Group Chat Privacy Mode
Telegram has a privacy mode setting for bots in group chats. When privacy mode is enabled (the default), your bot only receives messages that are commands (starting with /) or messages that mention the bot directly. When privacy mode is disabled, your bot receives all messages in the group. Your privacy policy should clearly state whether your bot uses privacy mode and, if disabled, explain why your bot needs access to all group messages.
You can check and configure your bot's privacy mode through BotFather using the /setprivacy command. Group administrators can also see whether your bot has privacy mode enabled or disabled when adding it to their group.
Telegram Bot API Data Flow
Understanding how data flows between Telegram and your bot is essential for writing an accurate privacy policy. The Bot API supports two methods for receiving updates, and each has different privacy implications.
Polling (getUpdates)
Your bot periodically calls the getUpdates endpoint to fetch new messages from Telegram's servers. Data temporarily resides on Telegram's infrastructure until your bot fetches it. This method is simpler to set up and does not require a public-facing server, but introduces a delay between when a user sends a message and when your bot processes it. From a privacy perspective, polling means data passes through Telegram's servers before reaching yours.
Webhooks (setWebhook)
Telegram sends updates directly to your server via HTTPS POST requests. This requires a publicly accessible server with a valid SSL certificate. Updates arrive in real-time, making webhooks the preferred method for production bots. From a privacy perspective, your server's IP address, hosting provider, and geographic location become part of the data processing chain. Your privacy policy must disclose where your webhook server is hosted and what happens to data once it arrives.
Regardless of which method you use, Telegram retains undelivered updates for up to 24 hours. After your bot confirms receipt (either by fetching via getUpdates or by responding with a 200 status to a webhook), Telegram removes the update from its queue. Your privacy policy should note this temporary Telegram-side retention.
Did you know?
When you set up a webhook, Telegram verifies your SSL certificate and only sends data over encrypted HTTPS connections. You can also provide a self-signed certificate for additional security. However, your webhook URL itself can reveal information about your infrastructure. If your webhook URL contains your bot token (a common pattern), anyone who discovers the URL could potentially intercept updates. Always use a secret path in your webhook URL and never expose your bot token publicly.
For details on general app privacy policy requirements, including what GDPR and CCPA require for software applications, see our dedicated guide.
Payment Processing via Telegram Payments API
If your bot accepts payments through Telegram's built-in Payments API, your privacy obligations increase significantly. Telegram supports payments through third-party providers like Stripe, Yookassa, Sberbank, and others. Your bot acts as a merchant, Telegram acts as an intermediary, and the payment provider processes the actual financial transaction.
What Payment Data Your Bot Receives
- Shipping address: If your bot sells physical goods, users provide their shipping address through the Telegram payment flow
- Order details: Your bot receives the items ordered, quantities, and total amount through pre-checkout and successful payment updates
- Payment provider charge ID: A unique identifier for the transaction from the payment provider (e.g., Stripe charge ID)
- Telegram payment charge ID: Telegram's own identifier for the payment transaction
- Email and phone (optional): If requested during checkout, users can provide their email and phone number
Critically, your bot does not receive credit card numbers or sensitive payment credentials directly. Those are handled by the payment provider. However, you must still disclose in your privacy policy that payment data flows through Telegram to the payment provider, name the specific provider you use, and link to their privacy policy.
Payment privacy tip
If your bot uses Telegram Payments with Stripe, your privacy policy must mention both Telegram (as the intermediary) and Stripe (as the payment processor). Include links to both Telegram's privacy policy and Stripe's privacy policy. Users should understand exactly who handles their financial data at each step of the transaction.
Webhook and Server Data
If your bot uses webhooks, your server infrastructure becomes a critical part of your privacy disclosure. Unlike polling, where your bot fetches data from Telegram's servers, webhooks mean Telegram pushes data directly to your server. This has several privacy implications.
What Your Privacy Policy Must Disclose About Your Server
- Hosting provider: Name the cloud provider or hosting service where your bot runs (AWS, DigitalOcean, Hetzner, Railway, Vercel, etc.)
- Server location: Specify the geographic region of your server, as this determines where user data is processed and stored
- Server logs: Disclose whether your server logs incoming requests, as webhook payloads contain personal data (user IDs, messages)
- SSL/TLS encryption: Confirm that data in transit is encrypted via HTTPS, which Telegram requires for webhooks
- Data retention on server: Explain how long webhook data persists in your server's memory or logs before being discarded
If your server is hosted in the EU, data transfer is straightforward for EU users. If your server is outside the EU (e.g., in the US), you need to address GDPR cross-border data transfer requirements in your privacy policy. This typically involves relying on Standard Contractual Clauses (SCCs) provided by your hosting provider. For a SaaS privacy policy reference, see our dedicated guide covering server-side data processing obligations.
Bot Store and BotFather Requirements
BotFather is the official Telegram bot for creating and managing your bots. While BotFather does not currently enforce a mandatory privacy policy field the way some app stores do, there are several places where you should make your privacy policy visible and accessible.
Where to Link Your Privacy Policy
- Bot description: Use /setdescription in BotFather to include a mention of your privacy policy URL in your bot's description
- Bot about text: Use /setabouttext in BotFather to add your privacy policy link in the about section visible on your bot's profile
- /privacy command: Implement a /privacy command in your bot that returns a link to your full privacy policy
- /start message: Include a brief privacy notice and link in the welcome message users see when they first interact with your bot
Telegram has been increasingly focused on user privacy as a platform differentiator. Bot developers who proactively demonstrate privacy compliance are better positioned if Telegram introduces stricter bot review requirements in the future, which many in the developer community anticipate.
Q: Can BotFather's privacy mode replace a privacy policy?
No. BotFather's privacy mode controls what messages your bot receives in group chats, but it does not replace a privacy policy. Privacy mode is a technical setting that limits data access. A privacy policy is a legal document that explains your data practices. You need both: privacy mode as a technical safeguard and a privacy policy as a legal disclosure.
GDPR Compliance for Telegram Bot Developers
Telegram has a massive user base in Europe, particularly in countries like Germany, Italy, Spain, and across Eastern Europe. If your bot is publicly accessible, it almost certainly has EU users, which means GDPR applies to your data processing activities.
GDPR Requirements for Bot Developers
- Lawful basis: Identify your legal basis for processing. For most bots, this is either consent (user initiates interaction) or legitimate interest (bot provides a service the user requested)
- Data minimization: Only collect and store data that is strictly necessary for your bot's functionality. Do not log everything "just in case"
- Transparency: Your privacy policy must clearly explain what data you process, why, how long you keep it, and who you share it with
- User rights: You must provide mechanisms for users to access, correct, delete, and export their data. A /deletedata command is a practical implementation
- Data protection: Implement appropriate technical measures to secure user data, including encryption at rest and in transit
- No selling data: GDPR strictly regulates data sharing. Selling Telegram user data without explicit consent would be a serious violation
Did you know?
Under GDPR, when a user blocks your Telegram bot or deletes their Telegram account, you should treat this as a withdrawal of consent (if consent is your legal basis). This means you should delete or anonymize any stored data for that user within a reasonable timeframe. Implementing a periodic check for inactive users and purging their data is a good practice that demonstrates GDPR compliance.
For a comprehensive GDPR privacy policy template, including all 12 required sections, see our dedicated guide. It covers everything from data categories and legal bases to retention periods and cross-border transfers.
Common Mistakes Bot Developers Make
These are the five most common privacy policy mistakes Telegram bot developers make, along with why each one can cause problems with privacy regulators or user trust.
Mistake: "My bot only reads messages, it does not collect data"
Reading a message is processing personal data under GDPR. When your bot receives an update from the Bot API containing a user ID, first name, and message text, it has processed personal data regardless of whether it saves anything to a database. Your privacy policy must account for this processing, not just permanent storage.
Mistake: "Telegram handles privacy, not me"
Telegram's privacy policy covers Telegram's relationship with its users. Your bot is a separate service that receives data through the Bot API. You are an independent data controller under GDPR. Telegram provides the platform and the API. You provide the service. Both need their own privacy policies explaining their respective data handling practices.
Mistake: "I disabled privacy mode, but I do not mention it"
If your bot has privacy mode disabled, it receives every message in every group it is in. This is a significant data collection expansion that must be disclosed. Group members may not realize your bot can read all their messages, not just commands. Your privacy policy must clearly state that privacy mode is disabled and explain why your bot needs access to all group messages.
Mistake: "I use payments but only mention Stripe, not Telegram"
Telegram Payments involve three parties: your bot, Telegram as intermediary, and the payment provider. All three must be disclosed. Telegram processes payment data before routing it to the provider. If you only mention Stripe in your privacy policy but not Telegram's role, your disclosure is incomplete. Users should understand the full payment data chain.
Mistake: "I do not need to worry about data deletion"
Under GDPR, users have the right to request deletion of their personal data (the "right to be forgotten"). If your bot stores any user data, you need a mechanism to delete it on request. Implementing a /deletedata or /forgetme command is a practical approach. Your privacy policy must explain how users can exercise this right and the timeframe for processing deletion requests.

How to Create a Privacy Policy for Your Telegram Bot (6 Steps)
Follow these steps to create a privacy policy that complies with GDPR, CCPA, and covers all Telegram-specific data processing your bot performs.
Audit all data your bot receives from the Telegram Bot API
Review every update type your bot handles: messages, inline queries, callback queries, shipping queries, and pre-checkout queries. Document the user fields each update contains (user ID, first name, last name, username, language code). Note any special data types like location, contact, photos, or documents.
Map what data your bot stores and where
Review your database schema and any persistent storage. Document every table or collection that contains user data: user preferences, conversation state, command history, or user-submitted content. Note the database type (PostgreSQL, MongoDB, SQLite, Redis) and hosting provider. Record the geographic region, as this affects GDPR data transfer requirements.
Identify all third-party services and payment providers
List every external service your bot integrates with beyond the Telegram Bot API. This includes database hosting (MongoDB Atlas, Supabase), payment processors (Stripe, Yookassa via Telegram Payments), external APIs (weather, translation, AI services), analytics, error tracking (Sentry), and hosting providers. Each service receiving user data is a sub-processor.
Generate your privacy policy
Use a privacy policy generator to create a comprehensive policy. Input the data types, storage methods, third-party services, payment processing details, and your contact information. The generator produces a complete policy covering GDPR, CCPA, and Telegram-specific requirements.
Host your privacy policy at a permanent URL
Publish your policy at a stable, publicly accessible URL. Your bot's website or landing page is ideal. A GitHub Pages site works well for open-source bots. The URL must remain accessible long-term, so avoid platforms that might change URLs or remove content.
Link the policy in your bot's description and commands
Update your bot's description in BotFather to mention the privacy policy URL. Add a /privacy command that returns the link. Include a brief privacy notice in your /start welcome message. This ensures users can always find your policy, and similar to Slack app requirements, accessibility is key to compliance.
The Easiest Way to Get a Telegram Bot Privacy Policy
Most Telegram bot developers are programmers, not lawyers. Writing a privacy policy from scratch requires understanding GDPR, CCPA, and how they apply to the Telegram Bot API specifically. Copying another bot's privacy policy is a copyright and compliance risk because their data practices are different from yours.
A privacy policy generator lets you describe your bot's specific data handling and produces a complete, legally compliant policy in under 60 seconds. It covers all the sections required by GDPR (data categories, legal basis, user rights, retention periods), CCPA (California-specific disclosures), and Telegram-specific concerns (Bot API data, webhooks, payments, inline queries).
The generated policy is ready to host on your bot's website and link through BotFather. It includes all the disclosures needed for GDPR compliance and can be updated whenever your bot's data practices change.
Frequently Asked Questions
Do Telegram bots need a privacy policy?
Yes. Every Telegram bot processes personal data (user IDs, names, messages) through the Bot API. Under GDPR and other privacy laws, this processing must be transparent. A privacy policy is the standard way to meet this transparency requirement. It is also expected by bot directories and builds trust with users.
What data does a Telegram bot collect?
At minimum, every bot receives user IDs, first names, and chat IDs through the Bot API. Depending on interactions, bots may also receive usernames, last names, language codes, message text, photos, location data, phone numbers (via contact sharing), inline query text, and payment information.
Does the Telegram Bot API share user phone numbers with bots?
No, not by default. Bots only receive phone numbers if a user explicitly shares their contact using the request_contact keyboard button. This requires active user consent. If your bot requests or receives phone numbers, your privacy policy must disclose this collection of sensitive personal data.
How does Telegram Payments affect my bot's privacy policy?
Telegram Payments involve three parties: your bot, Telegram (intermediary), and the payment provider (Stripe, Yookassa, etc.). Your privacy policy must name all parties, explain what transaction data your bot receives, and link to the payment provider's privacy policy. Credit card numbers are handled by the provider, not your bot.
Do I need GDPR compliance for my Telegram bot?
If your bot has any users in the EU or EEA, GDPR applies. Given Telegram's large European user base, most public bots will have EU users. GDPR requires a lawful basis for processing, transparent privacy information, user rights mechanisms, and appropriate security measures.
What is the difference between polling and webhooks for privacy?
With polling, your bot fetches updates from Telegram's servers. With webhooks, Telegram pushes updates to your server. Webhooks mean your server infrastructure (hosting provider, location, SSL certificate) becomes part of the data processing chain and should be disclosed in your privacy policy.
How do I create a privacy policy for my Telegram bot?
Document your bot's data handling (what it receives, stores, and shares), then use a privacy policy generator to produce a complete, compliant policy. Host it at a permanent URL and link it through BotFather and a /privacy command.
