PreTel Privacy Policy
This Privacy Policy sets out how we,
“Telecom Apps Development”, use and protect your personal data
that you provide to us, or that is otherwise obtained or generated by us, in
connection with your use of cloud-based messaging services (the “Services”).
For the purposes of this Privacy Policy, ‘we’, ‘us’ and ‘our’
refers to Telecom Apps Development, and ‘you’ refers to you,
the user of the Services.
PreTel is a communication app based on Telegram api. You provide your mobile number and basic account data
(which may include profile name, profile picture and about information) to
create a Telegram account. We do not collect, store, or use any of this
information.
When you enable 2-step-verification
for your account or store documents using the Telegram Passport feature, you
can opt to set up a password recovery email. We do not collect, store, or use
any of this information.
PreTel is a cloud service based on Telegram api.
Telegram store messages, photos, videos and documents from your cloud chats
on Telegram servers so that you can access your data from any of your devices
anytime without having to rely on third-party backups. All data is stored
heavily encrypted on Telegram servers. We do not collect, store, or use any of
this information, and we do not know who or when you messaged via cloud chats.
Secret chats use end-to-end
encryption. This means that all data is encrypted with a key that only you and
the recipient know. There is no way for us or anybody else without
direct access to your device to learn what content is being sent in those
messages. We do not store your secret chats on our servers. We do not collect,
store, or use any of this information. and we do not know who or when you
messaged via secret chats.
When you send photos, videos or
files via secret chats, before being uploaded to Telegram servers, each item is
encrypted with a separate key, not known to the server. This key and the file’s
location are then encrypted again, this time with the secret chat’s key — and
sent to your recipient. Your recipient can then download and decipher the file.
This means that the file is technically on one of Telegram’s servers, but it
looks like a piece of random indecipherable garbage to everyone except for you
and the recipient. We don’t know what this random data stands for and we have
no idea which particular chat it belongs to. We periodically purge this random
data from our servers to save disk space. We do not collect, store, or use any
of this information.
In addition to private messages, PreTel also supports public channels and public groups.
All public chats are cloud chats. Like everything on PreTel,
the data you post in public communities is encrypted, both in storage and in
transit — but everything you post in public will be accessible to everyone. We
do not collect, store, or use any of this information.
PreTel uses phone numbers as unique identifiers so that it is easy
for you to switch from SMS and other messaging apps and retain your social
graph. We ask your permission before syncing your contacts.
Telegram stores your up-to-date
contacts in order to notify you as soon as one of your contacts signs up for PreTel and to properly display names in notifications. We
do not store any of this data about you or your contacts
You can always stop syncing contacts
or delete them from Telegram's servers in Settings > Privacy & Security
> Data Settings.
If you share a location in a chat,
this location data is treated like other messages in cloud or secret chats
respectively.
If you share your Live Location in
any chat or turn on ’Make Myself Visible’ in People Nearby, PreTel will use your data to display your location to
those users with whom you are sharing it, even when the App is closed – for as
long as you keep these optional features activated.
