LangPlant

PRIVACY POLICY

Last Updated: 20 November 2025

This Privacy Policy explains how LangPlant (“the App”, “the Service”, or “the Developer”) collects, uses, and protects information when you use the LangPlant mobile application and the website located at https://langplant.com.

LangPlant is designed as a privacy-first educational application. The App does not require account creation and does not collect personal identifiers such as your name, email address, phone number, or contact list. Most learning statistics and progress data are stored locally on your device and remain fully under your control.

If you enable iCloud Sync in the App settings, certain learning statistics and progress data may also be stored in your personal Apple iCloud account. This syncing is performed by Apple’s infrastructure. The Developer does not operate or control iCloud and has no ability to access, view, or retrieve any data stored in your iCloud account.

By using the Service, you acknowledge that you have read and understood this Privacy Policy.

1. GENERAL

This Privacy Policy applies exclusively to the LangPlant iOS application (“the App”, “the Service”). Its purpose is to explain what information the App may handle, how such information is processed, and what privacy choices are available to you as a user.

The LangPlant website (langplant.com) is not covered by this Privacy Policy in the same way as the App, because the website does not process, collect, store, or transmit any personal information. The website consists solely of informational pages. It uses only essential cookies required to remember your selected interface language; no analytics, tracking scripts, third-party tags, or advertising technologies are present.

LangPlant is designed as a privacy-first educational application that minimizes data processing to the greatest extent possible. The App does not require account creation and does not collect identifiers such as your name, email address, phone number, or contacts. Learning statistics are stored locally on your device, and—if you enable the optional iCloud Sync feature—may be stored in your personal iCloud account, which the Developer cannot access.

By installing, accessing, or using the App, you acknowledge that you have read and understood this Privacy Policy.

2. DATA WE DO NOT COLLECT

LangPlant is intentionally designed to avoid collecting personal data whenever possible.

The App does not request, collect, store, transmit, or otherwise process any of the following information:

  • Name, surname, or any form of real-world identity
  • Email address
  • Phone number
  • User accounts, login systems, or authentication identifiers
  • Precise or approximate geolocation data
  • Contact lists or address book data
  • Photos, media, files, or device storage contents
  • Advertising identifiers (IDFA / Ad ID)
  • Behavioral analytics or tracking for profiling
  • Third-party cookies, tracking cookies, or marketing pixels
  • Social logins or data from external identity providers
  • Any biometric identifiers
  • Payment information (all purchases occur through the Apple App Store; no payment data is visible to or accessible by the Developer)
The App does not perform:
  • Сross-app tracking
  • User profiling
  • Targeted advertising
  • Third-party data enrichment
  • Analytics based on personal identifiers
LangPlant operates entirely without user accounts and without any backend mechanism capable of identifying a person based on App usage.

3. DATA WE ACTUALLY COLLECT

LangPlant processes only the minimum amount of information required for basic operation of the App and server-side answer checking. The App does not collect personal identifiers and does not create user accounts. All processing described below is fully detached from any personally identifiable information.

3.1. Data Stored Locally on Your Device
The App maintains certain learning-related data directly on your device. This data is not transmitted to LangPlant servers, unless explicitly stated in this Policy.

The locally stored data includes:

  • Learned words and phrases
  • Learned grammatical structures
  • Error statistics and performance metrics
  • Session history
  • In-app preferences and configuration
This information remains stored exclusively on your device. It is not synced to LangPlant servers unless you enable iCloud Sync.

If iCloud Sync is enabled in the App settings, certain learning statistics may be stored in your personal iCloud account. iCloud is provided by Apple and is governed by Apple’s privacy policies.

The Developer cannot access your iCloud data.

3.2. Text You Send to the Server
When certain features are used, plain text may be transmitted to the LangPlant backend, including:
  • The text you enter as your translation / learning answer
  • The text you manually write in the “Report an Issue” form
The following data IS NOT transmitted:
  • Names
  • Email addresses
  • Phone numbers
  • Device IDs
  • Advertising identifiers (IDFA)
  • Precise or approximate location
  • Audio data
  • Speech recordings
  • Browser cookies
  • Social login data
  • Metadata, other than what your device and HTTP protocol inherently supply
What this text is used for:
  • Verifying correctness of your translation
  • Improving answer-checking algorithms
  • Processing issue reports you manually submit
How long this data is stored:
  • Answer-checking text and issue reports are stored indefinitely in internal databases used solely for improving algorithmic accuracy
  • All stored text is fully anonymized. The Developer has no technical ability to link any stored entry to any individual user
3.3. Server Technical Logs
For security, debugging, and preventing malicious activity, LangPlant servers maintain standard access logs. These logs may include:
  • IP address of the requesting device
  • Timestamp of the request
  • Requested path / endpoint
  • HTTP response code
  • Technical user-agent string (e.g., iOS version)
Server access logs may be retained indefinitely for strictly technical and security-related purposes, including:
  • ensuring server stability
  • diagnosing errors
  • detecting malicious activity (e.g., DDoS patterns)
  • maintaining the reliability of the Service
These logs are not linked to any in-app activity or stored answer data, and they are never used for profiling, tracking, analytics, marketing, or cross-service correlation.

3.4. Payments and Subscriptions
All purchases inside LangPlant are processed exclusively through Apple In-App Purchases.

This means:
  • LangPlant does not have access to your payment card
  • LangPlant does not receive your billing name
  • LangPlant does not receive your billing address
  • LangPlant does not process or store any financial information
Your payment interactions are governed solely by the Apple Media Services Terms and Conditions.

3.5. Summary of Actual Data Collected
For full clarity, here is the complete set of data types the App actually collects:

Collected:
  • Local learning statistics (stored on your device or, if enabled, in your personal iCloud)
  • Text you manually enter (translation answers and issue reports)
  • Server access logs (IP address and standard technical request data)
Not collected:
  • Personal identifiers (name, email, phone number)
  • Contacts
  • Location data
  • Audio or speech recordings
  • Photos or media
  • Device IDs or advertising identifiers
  • Cookies or tracking technologies
  • Behavioral analytics, profiling, or marketing data
  • Any other data listed in Section 2 (“Data We Do NOT Collect”)

4. HOW WE USE DATA

LangPlant uses the minimal amount of data it receives strictly for operational and technical purposes. No personal identifiers are collected, and no data is ever used for advertising, profiling, or cross-app tracking.

4.1. Service Operation
The App uses submitted text solely to ensure proper functioning of core features, including:

  • Verifying the correctness of your translation
  • Processing issue reports you choose to submit
This data is handled only to deliver the immediate functionality of the Service.

4.2. Improving Algorithmic Accuracy
Certain text you manually enter (answers and reports) may be retained in anonymized form to improve the quality of:
  • Grammar and structure parsers
  • Answer-checking logic
All stored text is fully anonymized. The Developer has no technical ability to associate any stored entry with an individual user.

No user-submitted sentence is ever used as app content, as learning material, or displayed to other users.

4.3. No Advertising, No Tracking
LangPlant does not use any data for advertising or behavioral analytics. The App performs:
  • No personalized ads
  • No third-party advertising integrations
  • No cross-app or cross-service tracking
  • No profiling based on App activity
Server logs and anonymized answer data are used strictly for technical and security purposes, not for marketing or user behavior analysis.

5. LEGAL BASES FOR PROCESSING (GDPR)

LangPlant processes data only when one of the following legal grounds applies (GDPR, Art. 6):

  • Performance of a contract (Art. 6 (1)(b))
    Processing the text you submit is required to deliver the core functionality you explicitly request (answer checking, issue reporting).
  • Legitimate interest (Art. 6 (1)(f))
    Anonymized text and server logs are retained to improve algorithms, maintain security, and ensure the App’s stability.
  • Legal obligation (Art. 6 (1)(c))
    Data may be kept or disclosed when a competent authority lawfully requires it.
No other legal bases—such as consent for marketing or profiling—are relied upon, because no such activities exist in the App.

6. SHARING OF DATA AND THIRD-PARTY SERVICES

LangPlant does not sell user data, does not share data with advertising networks, and does not participate in any form of data brokerage. Any limited data sharing described below exists solely to operate the Service and is strictly constrained to technical providers acting on behalf of the Developer.

6.1. Apple Services
The App interacts with several Apple-operated systems:

  • App Store / In-App Purchases: All payments are processed exclusively by Apple. The Developer does not receive and cannot access your payment details, billing data, or Apple account information.
  • Apple App Store Analytics: Apple may provide the Developer with aggregated, non-identifying analytics (e.g., number of installs). These statistics do not include personal data.
  • Apple Speech Recognizer: Speech recognition in the App uses Apple’s on-device frameworks. We do not send audio to LangPlant servers. If the user participates in Apple’s optional “Improve Siri & Dictation” program, Apple may store anonymised audio based on the user’s Apple settings and consent — we have no access to such data.
6.2. Hosting Providers (Backend Infrastructure)
The LangPlant backend runs on standard hosting and cloud infrastructure providers. These providers may technically process:
  • Anonymized text you manually submit (answers, issue reports),
  • Server access logs (IP address + technical metadata),
only to the extent necessary for secure operation of the Service. Hosting providers act as data processors and do not have permission to use, access, analyze, or disclose this data for their own purposes.

6.3. TMDB (The Movie Database)
The App may download poster images and metadata for films and series from TMDB. No user data is ever sent to TMDB. All interactions are one-directional (read-only requests made by the App or server).

6.4. No Advertising, No Marketing Partners
LangPlant shares no data with:
  • Advertising networks,
  • Marketing partners,
  • Social networks,
  • Data brokers or analytics platforms.
6.5. Required Legal Disclosures
Data may be disclosed only if required by a lawful request from a competent authority. Such disclosures never involve learning statistics or personal identifiers, because the App does not collect them.

7. CHILDREN’S PRIVACY

LangPlant is designed to be suitable for users aged 9+. The App does not require account registration, does not collect personal identifiers, and does not process any information that could be used to identify or profile a child.

7.1. No Personal Data Collection
The App does not collect names, contact details, location data, photos, audio recordings, device identifiers, or any other personal information from children or adults. All learning statistics are stored locally on the device and remain fully under the user’s control.

7.2. No Tracking or Advertising
LangPlant performs no behavioral tracking, no analytics based on personal identifiers, and includes no advertising technologies. The App fully complies with the requirements for child-appropriate software by avoiding any form of targeted advertising, profiling, or cross-app tracking.

7.3. Optional 18+ Content Gate
Certain vocabulary examples within the App may include mature language. These examples are fully hidden by default and can only be enabled by manually switching an optional setting in the App. The Developer does not encourage or suggest enabling such content, and the App never displays mature content automatically.

7.4. External Services
If iCloud Sync is enabled, learning progress may be stored in the user’s personal Apple iCloud account. This data is processed solely by Apple, and the Developer has no access to it. No data is shared with third-party advertisers, analytics providers, or social platforms.

7.5. Compliance
The App is designed to meet the privacy expectations of child-appropriate applications under applicable regulations, including COPPA principles (United States) and GDPR requirements for children’s data within the European Union, by not collecting personal data in the first place.

If you believe that a child has submitted any information to the Service, please contact the Developer at support@langplant.com so that the information can be removed. However, due to the App’s design, the Developer has no access to user-specific data and cannot identify individual users.

8. INTERNATIONAL TRANSFERS

LangPlant operates using cloud infrastructure that may be located in various regions, including the European Union, the United States, or other jurisdictions. Because of this, certain data described in this Privacy Policy may be processed on servers located outside your country of residence.

8.1. Nature of Transferred Data
The only data that may be transmitted to LangPlant servers consists of:

  • Text you manually enter (your translation attempt or issue report)
  • Standard technical request information (IP address, timestamp, HTTP metadata).
No personal identifiers (such as your name, email, phone number, or precise location) are transmitted. No audio, images, device IDs, or tracking identifiers are sent to the servers.

8.2. Security and Encryption
All data transmitted between the App and the servers is protected using industry-standard HTTPS encryption. The Developer applies strict security measures to prevent unauthorized access or disclosure.

8.3. Data Minimization
LangPlant follows a strong data minimization principle. Requests to the backend typically contain only 1–3 KB of plain text and receive responses of a similar size. No additional metadata, identifiers, or unnecessary information is attached or collected.

8.4. Legal Basis
International transfers occur solely for the purpose of ensuring the technical operation of the Service. When applicable, such transfers rely on GDPR Art. 6(1)(b) (performance of a contract) and Art. 6(1)(f) (legitimate interest in maintaining a functional, stable, and secure service).

By using the App, you acknowledge that data described in this Policy may be processed in countries other than your own.

9. USER RIGHTS

Because LangPlant does not create user accounts and does not collect personal identifiers, most of the traditional data rights (such as requesting a full copy of your personal profile) do not apply in the usual way. The App is intentionally designed so that nearly all learning data stays on your device and remains fully under your own control.

9.1. Access to Your Data
All learning statistics, performance metrics, and progress information are stored locally on your device and are visible directly inside the App (in the Statistics section). The Developer does not have access to this information and cannot retrieve or export it on your behalf.

9.2. Deletion of Your Data
You may delete all locally stored App data at any time by:

  • Using an in-app option to remove all user data
  • Deleting the LangPlant application from your device
  • Manually clearing iCloud data in your Apple account settings (if iCloud Sync was enabled)
This action fully removes all learning statistics stored on your device or in your personal iCloud.

9.3. Server-Side Data
The only information that may be stored on LangPlant servers is:
  • Text you manually enter (translation attempts or issue reports)
  • Standard technical access logs (IP address, timestamp, HTTP metadata)
All such information is fully anonymized. Because no personal identifiers are ever collected, the Developer cannot reliably associate any stored text or logs with any individual user.

9.4. Your Rights Under Applicable Law
Depending on your jurisdiction (e.g., GDPR in the EU), you may have the right to:
  • Request information about whether we process any data related to you
  • Request deletion of any personal data you believe we may hold about you
  • Ask questions regarding our data practices
Because we do not create user accounts and do not collect identifiers, in most cases we cannot identify you in our systems. However, we will review and respond to all reasonable requests.

9.5. Contact for Data Questions
If you have any questions, concerns, or requests regarding privacy or data processing, you can contact us at: support@langplant.com.

We will make every reasonable effort to address your inquiry.

10. SECURITY

LangPlant implements technical and organizational measures to help protect the limited data it processes.

10.1. Encrypted Communication
All communication between the App and LangPlant servers is protected using HTTPS, preventing interception or unauthorized modification of transmitted data.

10.2. Restricted Server Access
Access to backend systems is strictly limited to authorized personnel and protected by industry-standard security controls. No third parties have access to server data except hosting providers acting as technical processors.

10.3. No Data Sharing
LangPlant does not sell, share, or disclose any data to advertisers, analytics networks, or external organizations for marketing or profiling purposes.

10.4. Minimal Logs and Retention
The Service retains only minimal technical logs required for security and stability (IP address, timestamp, request metadata). These logs are stored for operational and anti-abuse purposes and are not linked to personal identifiers.

11. DO NOT TRACK

LangPlant does not use tracking technologies for advertising, behavioral analytics, or cross-site identification. The App does not monitor your activity across other applications or websites.

Because the Service does not perform any such tracking, “Do Not Track” (DNT) signals sent by your browser or device do not alter how the App operates. The App already functions without tracking by design.

12. LINKS TO THIRD-PARTY WEBSITES

The App may contain links to third-party websites, resources, documentation pages, or open-source projects (for example, TMDB, GitHub, ChatGPT, or other developer resources). These external sites are not operated, owned, or controlled by the Developer.

When you follow a link to any external website, your use of that site is governed solely by the privacy policies, terms, and practices of the respective third party. The LangPlant Privacy Policy does not apply to your activities outside the App.

The Developer is not responsible for the content, privacy practices, security measures, or data processing performed by any third-party website or service. To the extent permitted by law, the Developer is not liable for any loss or damage resulting from your access to or use of external resources.

The App includes no advertising, tracking scripts, embedded marketing content, or commercial offers from third parties.

13. PRIVACY POLICY UPDATES

The Developer may update this Privacy Policy from time to time to reflect changes in the App’s functionality, legal requirements, or data processing practices. When updates are made, the “Last Updated” date at the top of this document will be revised accordingly.

If any changes materially affect how the App handles data, the Developer may provide an in-App notice or publish a notification on the LangPlant website to inform users of the update. Continued use of the Service after such changes take effect constitutes acceptance of the updated Privacy Policy.

14. CONTACT

If you have any questions, concerns, or requests related to this Privacy Policy or the handling of data within the App, you may contact the Developer at: support@langplant.com.

For matters related to abuse, security incidents, or copyright issues, you may also contact: abuse@langplant.com.

The Developer will make reasonable efforts to respond to all privacy-related inquiries.
