Linekind Privacy Policy
Version 1.0.2: free replies and weekly Plus
This section applies when version 1.0.2 is installed. It describes an update prepared for App Review, not a released update. Earlier versions keep their existing offer. For 1.0.2, the terms below about requiring an account and subscription for all AI, monthly-only subscriptions and no free trial are replaced by this section; other terms remain unchanged.
New users receive three complete AI reply sets in Chats once, without an account or subscription. A completed set contains three reply options. Failed requests, requests needing more context and no-reply results do not use a free set. Consent is still required before each request. Other AI tools require eligible Plus or connected access.
A random device credential is stored in iOS Keychain to identify the free allowance. The server keeps a pseudonymous allowance identifier, completed-request markers and counters, without conversation text. These small records have no automatic time-based deletion and prevent duplicate free allowances. Ordinary sign-out, account deletion or reinstalling does not reset the allowance; device erasure or Keychain loss may affect access. The free allowance is not linked to an Apple sign-in account. Contact support for privacy or access requests.
Linekind Plus Weekly is an auto-renewing subscription: eligible subscribers receive three days free, then US $4.99 per week. Apple shows the local price and whether you qualify before confirmation. The trial automatically renews into a paid weekly subscription unless canceled through Apple; cancel at least 24 hours before the trial ends to avoid renewal. The monthly option remains US $19.99 per month, with no trial. Existing monthly and legacy subscribers keep their terms.
Weekly Plus includes 100 completed sets in each verified subscription period, including the three-day trial, with a shared limit of 30 per UTC day. A trial period and a paid period are separate allowances; a trial is not a paid purchase. Unused sets do not roll over. Restoring or reinstalling does not add sets. Existing request-attempt limits remain. Manage or restore through My voice → Settings, and manage or cancel subscriptions in Apple settings. Deleting the app or Linekind account does not cancel an Apple subscription.
Navigation for your app version
The instructions below use the version 1.0 labels: Studio, Saved and Your space.
In version 1.0.1, open Chats for replies, Profile Workshop and Conversation Coach, and Practice for guided or custom practice and rehearsal. Open Chats → View all for the saved library. Open My voice → Settings (the gear icon) for account, membership, app language, privacy, deletion and Connected workspace controls described under Your space. Writing styles and context cards are in My voice.
Updated September 12, 2026.
Linekind helps adults write profiles and messages, review conversations and drafts, and practice what to say. You choose the information to include and decide whether to use the result. Linekind never sends a message or changes a dating profile for you. For privacy questions or requests, contact jorge@cerostudios.net.
Screenshots and text recognition
Linekind reads only the images you select, up to five at a time, using Apple's on-device text recognition. Original images are not uploaded to Linekind, OpenAI or Google, and your photo library is not scanned in the background. Review, correct and reorder the extracted text, identify speakers and remove private details before sharing. Combining images does not authorize an AI request. If the text exceeds a limit, shorten it yourself; Linekind does not silently cut it to fit.
In Build 11, the Share extension reads only the text or images you choose. It saves reviewed text to a protected, device-local Shared inbox for you to open in Linekind. It does not upload original images, read other apps in the background or send a message. Importing is separate from approving an AI request.
Text you approve for AI processing
After you review and consent, Linekind sends the approved text to its server and the provider named in that request. In version 1.0.1 and later, OpenAI handles replies, openers, invitations, reply refinements, Profile Workshop, Conversation Coach and practice feedback. Earlier versions use Google for Profile Workshop, Conversation Coach and practice feedback, as their consent screens state. The updated tools ask for fresh OpenAI consent; earlier Google consent is not reused. Profile Workshop can include your real details, existing profile text, question and goal. Conversation Coach uses the approved messages and context, plus your unsent draft when you choose draft review. Reply and practice requests can include conversation or setup text, your draft, editing instructions and writing preferences. The selected tone and output language accompany the request. Saving or editing locally does not send a new AI request.
Your optional profile name is not included in AI requests. Your optional writing sample stays local unless you enable sharing; it then accompanies approved reply and practice requests to the provider identified in the consent screen. Version 1.0.1 and later use OpenAI for both. A request may use two processing passes with the same provider to check details. This still uses one generation. Older app versions may use Google for replies, as their consent screen states.
Generation requests are not saved as cloud history or written to application logs. The separate optional cloud-saving action described below stores items you choose. OpenAI API data is not used for model training by default. We disable stored Responses; independent abuse-monitoring logs normally last up to 30 days, with longer retention possible for legal or safety reasons. Prompt-cache state can remain for up to 24 hours. This is not zero retention. Read OpenAI’s data controls.
For requests from earlier versions that identify Google, Google processes requests under its paid API terms: prompts and responses are not used to improve its products. Google retains prompts, context and responses for 55 days for abuse monitoring and legal requirements. Authorized personnel may review flagged content; these records may be used for policy-enforcement models. This is not a zero-retention service. Google may process information where it or its agents operate facilities. Read Google's paid-service terms and abuse-monitoring policy. Submit only information you have permission to use.
In Build 11, before-send meaning review and simulated, multi-turn rehearsal use OpenAI after confirmation. The request can include the messages, draft, practice turns, facts, writing samples and Spanish register choices you explicitly select. Stored styles and context cards are not automatically included. The consent screen identifies the provider for each tool. Version 1.0.1 and later use OpenAI for the guided tools as well, with fresh consent before submission.
Saved work on your device
Replies and their original drafts/instructions, profile drafts and results, coaching inputs/results, custom practice setups, practice attempts, favorites and writing preferences stay in protected files on this device, excluded from device backups. Practice history retains up to 200 attempts. Build 10 does not provide cloud history sync; Build 11 offers the separate, optional selected cloud copies described below. Saved drafts are not treated as sent messages. The device Keychain stores authentication credentials. Copying or pasting text into another app is subject to that app and the operating system's behavior.
Optional connected workspace · Build 11
These features apply only when available in your installed app. Build 10 keeps history on the device and does not offer a connected cloud workspace.
Connecting requires you to approve the matching device code on Linekind’s website. The web account and Apple sign-in remain separate logins. Linking writing access is another explicit action: we retain the verified account connection and encrypted session and purchase proof to check eligible access. Your web password is not entered in the app.
Cloud saving is off until you enable it. Then choose individual conversations, writing styles, context cards or rehearsals to upload. Their selected content is stored under your web account, encrypted with a server-held key; this is not end-to-end encryption. Connecting alone does not upload your library. Uploading or importing does not request AI output. Imports create separate local copies. Remove Shared inbox items in that inbox. Build 11’s Delete saved content also clears local rehearsals and the shared inbox; saved styles and context cards have their own controls in Your space.
Pausing cloud saving stops new uploads but keeps existing copies. Delete cloud copies separately; local deletion and native account deletion do not close your web account or erase its cloud copies. Disconnecting this device revokes its web session; removing a membership link stops access through that link. Neither action deletes cloud copies or cancels a subscription. Web account deletion, backup retention and retained billing records are explained in the web privacy notice.
Account, subscriptions, and service use
In Build 10, live AI requires Sign in with Apple and a verified active App Store subscription. Build 11 also supports eligible linked web writing access as described below. Apple sign-in creates a pseudonymous Linekind account; we do not request your name or email through it. The service retains hashed session credentials, encrypted Apple authorization credentials, verified purchase information and subscription-linked usage counters for access, security and account deletion. Apple handles payment; Linekind does not receive your card number.
RevenueCat manages subscription purchases, restoration and subscription analytics. It receives the pseudonymous account identifier, purchase information and device/app/store metadata, including Apple's identifier for vendor (IDFV). We do not send conversations, drafts, writing samples or screenshots to RevenueCat or use this data for advertising tracking. See RevenueCat's privacy policy.
We keep compact pseudonymous subscription-period identifiers, policy assignments and usage counters to provide the correct allowance and prevent duplicate grants after restoration, account recreation or payment recovery. These records do not contain your conversations, drafts or receipt bodies. They remain after account deletion and subscription expiry; the current system does not automatically delete them on a time schedule. They are separate from anonymous aggregate provider-usage statistics. Deleting your account does not cancel an Apple subscription or erase provider records independently retained under their policies.
Anonymous daily provider-call, token and cost-coverage counters help us understand service use. These aggregate counters contain no conversation text or account identifier and are separate from the subscription-linked allowance records.
The app does not include advertising tracking. If you email support, your email address and the information you choose to include are used to handle your request. Please do not send full private conversations, passwords, payment-card details, or sign-in codes.
Network security and reliability
Cloudflare protects and delivers connections to Linekind. It processes network information such as IP addresses, approximate country derived from IP, request paths, response status, and timing to secure the service and keep it available. Cloudflare retains security and traffic metadata under its own policies. Dashboard retention windows do not guarantee deletion from every provider system.
Native service application logs contain a random request identifier, route, response status, and duration. They do not contain conversation text, account identifiers, session credentials, or IP addresses. Logs rotate by size, currently up to three 10 MB files per environment. These operational records are separate from saved conversations and are not erased by clearing local history.
Your controls
You choose whether to submit text to AI processing. Without that consent, your text is not sent for a new AI request. You can edit or remove details before each submission.
You can remove individual saved results or practice attempts. Removing a custom setup leaves its previous feedback available; delete those attempts separately if desired. Your space → Delete saved content clears saved replies, practice history, profile drafts/results, coaching drafts/results and custom setups. It does not cancel a subscription or erase independently retained provider records.
Your space → Delete my account requests removal of Linekind sessions, local history/preferences and the Apple authorization used by Linekind. It also requests removal of the RevenueCat customer profile and purchase history for this app across test and production records. If remote cleanup is pending, the app says so and retains a minimal request for retry; sign-in remains unavailable until processing finishes. Deletion does not erase Apple's financial records, immediately erase independent provider retention or cancel your Apple subscription. Manage that subscription separately in Apple settings.
Compact subscription-period, plan and usage records remain to prevent duplicate allowances after account recreation or purchase restoration. They do not contain your conversations, and currently have no automatic time-based deletion. See the privacy policy for details.
Deleting local data or your Linekind account does not immediately erase records retained independently by Apple, OpenAI, Google, or other service providers under their policies and legal obligations. Contact us to request access, correction, or deletion of information we hold, or to exercise rights available under your local law. We may need to verify the request without asking for your password.
