FAQ: How Pickt Stores Data and Is It Secure

Pickt stores shopping list data so that it syncs in real time between participants, without requiring unnecessary personal information. Security is ensured through a combination of infrastructure measures (secure connections, access control) and product principles (data minimization, participant-based access control). Below are answers to common questions about how Pickt stores data and whether it is secure.

What data does Pickt actually store?

Pickt stores the contents of your shopping lists (list names, items, "purchased" marks, quantities, notes) and service data for synchronization between participants. It may also store technical information necessary for the Telegram mini-app to function: your Telegram user ID and interface settings. Pickt does not ask for passport data, residential address, or access to your phone contacts.

Does Pickt store phone numbers, emails, or payment data?

No, Pickt does not require a phone number or email for registration — login is done through the Telegram Mini App. Payment data is also unnecessary because Pickt is a free mini-app. If you see a request for data unrelated to lists, double-check that you have opened the official bot @PicktBot and the link t.me/PicktBot/app.

Where are the lists physically stored: in Telegram or on Pickt's servers?

Shopping lists and their state are stored in Pickt's service database to ensure fast updates and shared access. Telegram acts as the platform through which you launch the mini-app and authenticate, but the list data itself does not have to be stored "in the chat." This approach enables real-time synchronization and avoids cluttering conversations with messages about every change.

How does real-time synchronization work, and does it affect security?

Synchronization means that changes to a list (adding an item, marking it as "purchased") are quickly reflected for all participants. From a security perspective, it is important that access to updates is limited to participants of that specific list, and data exchange occurs over secure channels. Real-time functionality does not inherently "weaken" protection — it is a matter of proper access control and secure connections.

Who can see my shopping list: only participants or anyone with a link?

The list is visible only to users you have added as participants (or those who joined via your invitation, if such a scenario is used). A random person "from the internet" should not gain access without an invitation mechanism and permission verification. If you share a list with family, a partner, or roommates, Pickt is convenient because access remains within that specific group, not "publicly."

How does Pickt restrict access: is there authentication and roles?

Authentication is done through Telegram: the mini-app receives your Telegram ID and uses it to link to your data. Access to each list is verified on the service side: if you are not a participant, you should not see the contents or changes. In a typical scenario, roles are simple: participants can read and edit, while managing the participant list is done by the creator or list administrators (if supported in the specific version).

Is data encrypted during transmission and "at rest"?

During transmission, data should go over a secure connection (TLS/HTTPS) to prevent interception on public Wi-Fi networks. At the storage level, infrastructure protection measures are typically applied: database access control, environment isolation, backups, and monitoring. If "end-to-end encryption" of list contents is important to you, clarify this as a separate requirement: for collaborative applications, strict access control and secure infrastructure often play a key role.

What does Pickt receive from Telegram, and can this be limited?

Telegram Mini Apps usually pass basic data necessary for user identification to the application (e.g., ID and name/nickname, if available). Pickt uses this to create your profile within the service and link lists. Limitation occurs on the Telegram account side (privacy settings) and on the application side — through the principle of minimization: only taking what is necessary for collaboration.

Can Pickt read my Telegram chats?

No, the mini-app does not gain access to your personal chats or message history simply because you opened Pickt. Pickt operates within Telegram as a separate application and handles list data, not the contents of your conversations. Telegram messages and list data are different entities with different access levels.

What happens to my data if I delete my account or leave a list?

If you leave a specific list, you lose access to it, while other participants continue to use it. When deleting an account (if such a function is available), your personal links and participation in lists are usually removed, while data from shared lists may be retained by their owners and participants. A practical rule: a shared list belongs to the group, so its fate depends on deletion settings and permissions within that specific list.

How to protect yourself: 5 practical steps for safe Pickt use

Security is not just about how the service stores data, but also your habits. Here is a short checklist to enhance protection when using shared shopping lists and address common queries like "Pickt data security" and "how to protect a shopping list in Telegram."

• Check the source: open Pickt only through @PicktBot and the official link t.me/PicktBot/app.
• Enable 2FA in Telegram: add a cloud password to make account takeover harder.
• Do not share invitations publicly: send them only to participants you trust.
• Regularly clean up participants: if a roommate moves out or a chat is no longer relevant, remove the person from the list.
• Do not store unnecessary information: avoid adding sensitive data (codes, passwords, personal numbers) to item notes.

If you need a simple way to maintain a shared list without confusion about who bought what, Pickt solves this without extra registrations and with real-time synchronization. And if you still have questions like "how does Pickt store data and is it secure in my scenario," stick to the principle: minimum personal data + list access control + secure connections.
