Speakblend is a social language learning platform operated by UNIQUE CO (hereinafter referred to as "we" or "our"). We place the highest priority on safeguarding your privacy and personal data, and are committed to protecting your information at all times. This Privacy Policy outlines how we collect, use, and protect your information when you engage with our services.
Before using Speakblend, please carefully review this Privacy Policy. If you do not read and accept all terms within this agreement, please discontinue using Speakblend immediately. By creating an account or using Speakblend, you acknowledge that you have fully understood and accepted this Privacy Policy.
Part One: Definitions
User: refers to individuals or organizations that register, log in, use, browse, or obtain services under this policy (hereinafter referred to as "you" or "user").
Personal information: includes all information recorded electronically or through other methods that can identify a specific person when used alone or combined with other information, or that reflects the activities of a specific individual.
Part Two: Contents
This privacy policy will help you understand:
1. Information We Collect
(1) Account Registration
When you register for Speakblend, we collect your unique device identification code (such as Vendor ID or Android ID) to identify you as a Speakblend user. If you log in using Google, Apple ID, or other supported social platforms, we collect your unique identifier, email address, avatar, and nickname from these services to synchronize your data and enable multi-device login. After registering with a third-party account, it will be linked to your Speakblend account and stays linked until you delete your Speakblend account.
When creating your Speakblend profile, we collect: email address, username, display name, profile photo, gender, date of birth, nationality, native language, and languages you're learning. This information enhances your service experience and improves our language matching algorithms.
Speakblend does not ask for your mobile phone number. You sign up and log in with your email address and a one-time code sent to it, or with Google or Apple ID.
(2) Network and Operational Security
To protect your account and ensure system security, our servers automatically record information sent by your device ("log data"): the device model and name, platform, operating system version, app version, device identifiers, locale and time zone, and your IP address. Your precise location is recorded only with your consent, as described in (5) below.
(2a) Product Analytics and Crash Reporting (Self-hosted)
Speakblend operates its own analytics and crash-reporting pipeline. The mobile app sends telemetry to the Speakblend backend at api.speakblend.com; data is not shared with third-party analytics providers (such as Google Analytics or Firebase Crashlytics).
We collect the following telemetry to understand product usage, diagnose stability issues, and improve the experience:
- Anonymous device identifier (UUID generated by the app and stored in the device's secure storage)
- Per-launch session identifier
- Screen views with entry/exit timestamps and the time the screen was visible/active
- Scroll depth milestones for feed-style screens
- Generic in-app events (for example: button clicks, login, sign-up, send message)
- Platform, app version, OS version, device model
- Locale and timezone
- Your IP address, which is stored with the session, and the country code derived from it server-side
- Advertising identifier (IDFA on iOS, AAID on Android) only if you have explicitly granted the App Tracking Transparency / Limit Ad Tracking permission. We honour your operating-system tracking preferences.
- For crash reports: exception type, message, stack trace, and the technical context above; user identifier is included only if you are signed in.
All telemetry is rate-limited and validated server-side, transmitted over HTTPS, and stored in our PocketBase database. It is not deleted automatically when you delete your account. You can request export or deletion of this data at any time by contacting [email protected].
(3) Camera Functionality
After enabling camera permissions, you can take photos, upload, share, and use related features. We only access your camera when you actively engage with these functions in the app.
(4) Microphone Functionality
You can use the microphone for voice communication by enabling microphone permissions. We only access your microphone when you actively initiate voice features in the app. During voice calls, the audio from your microphone may be recorded for safety, as described in Section 3 (2).
(5) Geographic Location Information
With your consent, we record your geographic location to optimize language partner matching in your region and to show your location on your profile and on the Friends Map (see Section 4). Geographic location is sensitive information, and refusing to provide it will not affect core app functionality. You can adjust location permissions anytime in your device settings.
(6) Storage Permissions
When uploading profile pictures or sharing media content, we need access to your device storage/gallery. Refusing these permissions will limit media sharing capabilities but will not affect other Speakblend functions.
(7) Other Circumstances
According to relevant laws, regulations, and national standards, we may collect and use your personal information without prior authorization in the following situations:
- When directly related to national security or defense security
- When connected to public safety, public health, or major public interests
- When linked to criminal investigation, prosecution, trial, or judgment enforcement
- When necessary to protect your or others' vital interests (life, property, reputation) but consent is difficult to obtain
- When you have already made the information publicly available
- When collecting information from legally published sources like news reports or government disclosures
- When necessary for contract execution based on your request
- When required for maintaining service stability, such as resolving technical issues
- When conducting statistical or academic research in the public interest (with results anonymized)
- In other circumstances stipulated by laws and regulations
2. Information Storage
(1) Storage Methods and Duration
We store your information securely through local storage (app caching), databases, and server logs.
We only retain your personal information for the time necessary to fulfill our service purposes or as required by law. You can delete your posts, comments, chats, and account at any time. The next subsection describes what is removed and what is kept.
(2) Information Management and Retention
Legal obligations: We retain information when legally required, to enforce our Terms of Service, or to protect rights, property, and users.
Operational needs: Your chats, including the messages, photos, and voice messages in them, are stored on our servers so that they can be delivered to the other participants and kept as a chat history you can scroll back through and search. They stay stored until the chat is deleted. Deleting a chat removes it for every participant. When you delete or clear individual messages, they are hidden from view, but their content stays stored with the chat until the chat itself is deleted; when you edit a message, its earlier versions are kept with it. Your public information (profile and posts) remains until you delete it or your account. When you delete a post or a comment, it is removed from the app for everyone; deleting a post also removes its comments.
Safety and security: When a chat, post, comment, or account is deleted, we keep a copy of the deleted information for safety and security purposes, for example to review reports and abuse, and for the purposes described under Legal obligations above. This copy is not visible to other users, and only authorized Speakblend administrators can access it.
Account deletion: When you delete your account, your profile, posts, comments, likes, and notifications are removed from the app immediately, and your account is removed from other users' follower and following lists. Your chats with other people remain available to them, except unanswered introductions sent in your first 48 hours, which are deleted. As described under Safety and security above, we keep a copy of the removed information: your profile details and sign-in identifiers, posts, comments, likes, notifications, matching data, follow connections, and those introductions. We also keep a record of the deletion with a copy of your profile details and the reason you gave, together with the copies of deleted chats and the records described in Section 1 (2a).
(3) International Data Transfers
Speakblend operates globally, which may involve transferring data across international borders. Such transfers comply with applicable laws and are conducted securely. You can request information about your data transfers at any time.
(4) Personal Information Retention Period
Apart from voice call recordings, which are deleted after 30 days as described in Section 3 (2), Speakblend does not delete information on a fixed schedule. The following records are kept while your account exists and after you delete it, with no fixed end date, only for the purposes described under Legal obligations and Safety and security above:
- Login, session and device records (the log data in Section 1 (2))
- Subscription and purchase records (the payments themselves are processed and kept by Apple or Google)
- Reports, complaints and support requests
- The deletion record described under Account deletion above
- Copies of deleted chats, posts, comments, and accounts, described under Safety and security in (2) above
Everything else is kept or deleted as described under Account deletion above. You can ask what we keep about you, or ask us to delete it, at [email protected].
3. Information Security
(1) Data Protection Measures
We implement comprehensive technical and organizational safeguards to protect your data against unauthorized access, modification, distribution, or loss.
To secure data transmission against third-party access, we employ industry-standard encryption protocols including SSL and TLS encryption.
(2) Voice Calls
Speakblend offers voice calls only. To keep our users safe, voice calls may be recorded. The app asks for your consent to call recording once, before you use voice calls; if you do not agree, you can still use every other feature, but you cannot make or receive voice calls. While a call is being recorded, the call screen shows "Recorded for safety".
How recording works: Your app sends the audio from your own microphone to Speakblend's recording server, separately from the call itself. Recordings contain audio only, and nothing is recorded while you are muted. Calls with someone who uses an older version of the app without recording support are not recorded.
Use and access: Recordings are stored on Speakblend's servers and are not shared with third parties. They are not transcribed or analyzed automatically. They are listened to only when a report is made about a call or the people in it, and only by authorized Speakblend administrators; every playback is logged.
Retention: Recordings are deleted 30 days after the call, including when you delete your account. While one participant has an open report against the other, the recordings of their calls are kept until the report is closed.
We cannot prevent other users from recording or sharing conversations without permission, so please be careful when sharing personal information during voice calls. For questions about call recordings, contact [email protected].
(3) Security Incident Response
In case of data breaches or other security incidents, we will activate emergency protocols to contain the situation. We will promptly inform you about the incident and our remedial measures via push notifications, emails, or other appropriate channels. If individual notifications are impractical, we will issue public warnings through announcements.
(4) Managing Your Information
You can access your account information through [Profile→Settings→Account & Security] and modify your profile through [Profile→Edit profile]. You can manage user connections through [Profile→Following]. You can access and delete conversations in the [Messages] tab. If you find errors in your information, you can request corrections. You can disable app permissions (notifications, photos, camera, microphone) through your device settings. You can delete your account by following this path: [Profile→Settings→Account & Security→Delete your data and account]. Your profile, posts, and comments are removed from the app as soon as you confirm; Section 2 describes the records we keep. To request deletion without the app, see Delete Your Speakblend Account.
4. How We Use Information
We strictly adhere to laws, regulations, and user agreements, using collected information as described in this privacy policy to enhance your experience:
- We analyze demographic information to improve our language matching and service quality
- We send important notifications about service changes, policy updates, or account-related matters
- We check messages, posts, comments, profile text, and photos with automated moderation to keep the community safe; flagged messages and reports can be reviewed with the help of an AI model and by Speakblend administrators
- We do not treat log data as personal information unless combined with identifying information
- Public user information includes name, age, profile picture, current city, and time zone, but never your email address. If you allow location access, the map on your profile shows your location, and people who follow you can see you on their Friends Map. Turning on Hide exact location in [Profile→Settings→Privacy & Visibility] shows only your country on your profile and removes you from the Friends Map
- Device information and logs help us maintain service quality and security, and are anonymized when used in combination with personal information
5. Disclosure to Third Parties
(1) Principles
Your personal information is governed by Speakblend's privacy policies and is only used to provide or improve our services and advertising. We will not share your information with third parties for their marketing purposes.
Third-party services accessed through Speakblend are subject to their own terms and privacy policies (not this "Speakblend Privacy Policy").
We share information only for legitimate, necessary, and specific purposes. Third-party service providers must fulfill confidentiality obligations and implement appropriate security measures.
Analytical information is collected and used in aggregated form that cannot identify individual users.
(2) Third-party SDK Integration
Speakblend integrates various third-party SDKs for specific functionalities. These SDKs may collect certain information as detailed below:
- Firebase Cloud Messaging (by Google): Used only for delivering push notifications. Speakblend no longer uses Firebase Analytics or Firebase Crashlytics; product analytics and crash reports are now collected directly by Speakblend's own backend (see Section 2a).
- Google Sign-In & Apple Sign-In: Used to provide secure social authentication.
- RevenueCat: Used to manage app subscriptions and in-app purchases. It receives your account identifiers and basic account details such as your email address, display name, username, languages, and country.
- OpenStreetMap & Nominatim: Used for displaying maps and providing location-based language matching services.
- Device Info Plus: Used to identify device hardware characteristics for security and session management.
When you use translation or voice message transcription, and when content is reviewed by AI moderation, the text or audio involved is sent to the translation, transcription, or AI service provider that processes it.
Some accounts on Speakblend are operated by Speakblend and send automated, AI-generated messages. When you chat with one of these accounts, the messages and photos you send in that chat are processed by Google's AI service (Gemini) to generate its replies.
Our website, speakblend.com, uses Google Analytics, which stores cookies in your browser and sends Google information about your visit, such as the pages you view, your device and browser, and how fast the pages load, so that we can understand how the site is used. The website also stores your language or region choice in a cookie when you pick one.
You can edit your profile through [Profile→Edit profile] and hide personal data in [Profile→Settings→Privacy & Visibility]. You can also request account deletion or information changes by email at [email protected].
6. Children's Information Policy
Speakblend is only for adults. You must be at least 18 years old to create an account and use Speakblend; sign-up asks for your date of birth and does not allow anyone under 18 to register. We do not knowingly collect personal information from anyone under 18.
If you are a parent or guardian and believe that a person under 18 is using Speakblend, please contact [email protected].
