MemoChat processes and stores your Personal Data only for the period of time required to achieve the respective processing purpose or for as long as a legal retention period (in particular Estonian commercial and tax law) exists. Once the purpose has been achieved or the retention period has expired, the corresponding data is routinely deleted.

a) Contacting us
If you contact us, we process the following data from you for the purpose of processing and handling your request: first name, last name, e-mail address, and, if applicable, other information if you have provided it, and your message. The legal basis for the data processing is our obligation to fulfill the contract and/or to fulfill our pre-contractual obligations (Art. 6 para. 1 lit. b GDPR) and/or our overriding legitimate interest in processing your request (Art. 6 para. 1 lit. f GDPR).
b) Profile and account
If you create a user account, you will receive a unique ID from us and you are required to provide a username, nickname, and public ID. You may optionally add a profile photo. This allows us to identify you as a user and gives you the opportunity to manage your account, use our services and manage your purchases. Within your profile you are able to delete your account at any time. Your data will be processed on the basis of contractual necessity (Art. 6 para. 1 lit. b GDPR) and your consent (Art. 6 para. 1 lit. a GDPR).
c) When using our services
We process the data of our registered users in order to be able to provide our contractual services as well as to ensure the security of our services and to be able to develop it further. The required information is identified as such in the context of the information required for the provision of services and billing.
Of course, in the course of operating the Services, we also process your chats with other users and the content you transmit.
Our Security Model:
- Text Messages: Encrypted using AES-256-CBC with salt on our servers (server-side encryption). Messages are encrypted when stored and decrypted when retrieved by users.
- Files and Audio Messages: Encrypted on your device before upload using unique per-chat encryption keys. We cannot decrypt these files as the encryption occurs client-side before reaching our servers.
- Data in Transit: All communications are secured using HTTPS/TLS encryption.
Some of the Personal Data you provide may be considered "special" or "sensitive". This includes Personal Data concerning for example your health, racial or ethnic origins, sexual orientation, and religious beliefs. By choosing to provide this data, you consent to our processing of that data.
You have choices about the Personal Data you upload and share. You don't have to provide Personal Data; however, Personal Data helps you to get more from our Services. It's your choice whether to include special category data and to make that special category data public. Please do not upload or add data that you would not want to be available.
The legal basis for the processing of your personal and special category data is the establishment and implementation of the user contract for the use of the service as well as your consent. We store the data until you delete your user account. Insofar as legal retention periods are to be observed, storage also takes place beyond the time of deletion of a user account.
You may withdraw your consent and request us to stop using and/or disclosing your personal and special category data by submitting your request to us in writing to info@memochat.net.
Duration of data storage
We only store Personal Data for as long as it is necessary for the purposes for which it is processed or for as long as any consent you have given us has been revoked by you. Insofar as statutory retention obligations must be observed, the storage period for certain data may be up to 10 years, irrespective of the processing purposes.
Specific retention periods:
- Account Data: Retained until you delete your account, at which point personal data is anonymized
- Message Data: Retained based on user settings, with options for 24-hour deletion, 1-week deletion, 1-month deletion, or longer retention for active accounts. All message data is deleted upon account deletion
- Log and Usage Data: Retained for up to 12 months to aid performance and troubleshoot issues
- Push Notification Tokens: Expire with the session or upon logout
Obligation to provide Personal Data
You are not obliged to provide us with Personal Data. However, depending on the individual case as described above, the provision of certain Personal Data may be necessary for the provision of the services. If you do not provide us with this Personal Data, we may not be able to provide the requested service.
Do Not Sell
We do not sell data to third parties.
Authorizations and Access
We may request permission to store your APP data including your Internet Connection and Network, Camera, Audio, Video, Photos and Gallery of your device. The legal basis for data processing is our legitimate interest and the provision of contractual or pre-contractual measures. You can deny access on your device via the Settings/Notifications/ options of your device; however, this means that our APP may not function as intended.
Push messages
When you use the app, you will receive so-called push messages from us, even if you are not currently using the App. These are messages that we send you as part of the performance of the contract. You can adjust or stop receiving push messages at any time via the device settings of your device.
Transfer of Personal Data
We will not disclose or otherwise distribute your Personal Data to third parties unless this:
- Is necessary for the performance of our services,
- You have consented to the disclosure, or
- The disclosure of data is permitted by relevant legal provisions.
However, we are entitled to outsource the processing of your Personal Data in whole or in part to external service providers acting as processors within the framework of Estonian law and GDPR.
Our main third-party partners include:
- Firebase (Google LLC) for notifications and user engagement analytics
- Amazon Web Services (AWS) for secure server hosting
- Synervoz SDK for enhanced communication features
These providers may process data outside the EU. We implement appropriate safeguards, including Standard Contractual Clauses (SCCs), to ensure GDPR compliance.
The service providers commissioned by us however will process your data exclusively in accordance with our instructions and we remain in accordance with Estonian law and the GDPR responsible for the protection of your data.
We may also disclose Personal Data to third parties if we are legally obliged to do so e.g., by court order or if this is necessary to support criminal or legal investigations or other legal investigations or proceedings at home or abroad or to fulfill our legitimate interests.

Finally, you also have a right to object according to Art. 21 GDPR. This applies, on grounds relating to data processing on the basis of my legitimate interest and also to profiling.
If you object, we will no longer process your Personal Data unless we can demonstrate compelling legitimate reasons for the processing which override your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.
Please contact us at any time with questions and suggestions regarding data protection and to enforce your rights as a data subject.
Security
State-of-the-art internet technologies are used to ensure the security of your data. We employ robust measures to protect your data:
Hybrid Encryption Model:
- Text Messages: Server-side encryption (SSE) using AES-256-CBC with salt. Each message is encrypted differently using unique salt values.
- Files and Audio Messages: Client-side encryption with per-chat keys before S3 upload. We cannot decrypt these files as encryption occurs on your device.
- Data in Transit: HTTPS/TLS encryption for all communications.
- Data Fragmentation: S3 file encryption and segmentation for enhanced data security.
For secure storage of your data, the systems are protected by firewalls that prevent unauthorized access from outside. In addition, technical and organizational security measures are used to protect the Personal Data you have provided against accidental or intentional manipulation, loss, destruction, or access by unauthorized persons.

Withdraw your consent
You may withdraw your consent and request us to stop using and/or disclosing your Personal Data for any or all purposes by submitting your request to us using info@memochat.net.
