Privacy Policy
You don't have to take our word on all of this. Yllo is an open source project. Anyone can study our API, Protocol and Source Code and make an informed decision.
1. Sharing data
We never share your data with anyone. To this day, we have disclosed 0 bytes of user data to third parties, including governments.
2. Storing data
Yllo only stores the data it needs to function properly — for as long as you want Yllo to function. This application requires correct access to contacts. Provide these permissions to invite friends to the app, write to them and receive notifications when they send you messages. Your personal data will be stored on our distributed server.
Cloud Chats
Yllo is a cloud service. We store messages, photos, videos and documents from your cloud chats on our distributed servers, so that you can access your data from any of your devices anytime and use our instant server search to quickly access your messages from way back. All data is stored heavily encrypted and the encryption keys in each case are stored in several other DCs in different jurisdictions. This way local engineers or physical intruders cannot get access to user data.
Chats
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 chats on our servers. We also do not keep any logs for messages in chats, so after a short period of time we no longer know who or when you messaged via chats. For the same reasons chats are not available in the cloud — you can only access those messages from the device they were sent to or from.
Media in Chats
When you send photos, videos or files via chats, before being uploaded 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 chat’s key — and sent to your recipient. He can then download and decipher the file. This means that the file is technically on one of Yllo’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.
Contacts
Yllo uses phone numbers as unique identifiers, so that it is easy for you to switch from other messaging apps (SMS, WhatsApp, etc.) and retain your social graph. We ask your permission before syncing your contacts.
We store your contacts in order to notify you as soon as one of your contacts signs up for Yllo and to properly display names in notifications. We only need the phone number and name (first and last) for this to work and store no other data about your contacts.
3. Deleting data
Accounts
If you want to delete your account, you can do this by writing Yllo io. Deleting your account permanently removes all your messages, groups and contacts. This action must be confirmed via your Yllo account and cannot be undone.
Messages
Everything you delete is deleted forever.
When you delete a message, you delete it from your message history. This means that a copy still stays on the storage as part of your partner‘s message history. As soon as your partner deletes it too, it’s gone forever.
4. Payment information
The Payment Platform for Bots is available to users as of Yllo. Yllo does not process payments from users and instead relies on different payment providers around the world. It is the payment providers that handle and store your credit card details. Neither Yllo nor the merchants on the platform (bot developers) have access to this information.
Credit card information
When making a purchase, you enter your credit card details into a form supplied by the payment provider that will be processing the payment, and this information goes directly to the payment provider‘s server. Your credit card information never reaches Yllo’s distributed servers. We do not access and do not store your credit card information.
Clearing payment information
You can clear all payment information associated with your account at any time by going to Yllo Wallet and selecting ‘Clear Payment & Transaction Info’. If you choose to remove your payment information, we will delete your stored shipping info from all providers and ask the providers to remove information they store.
