Preplet

Terms of Service

1. Content Usage Policy

Preplet is designed to help students and learners generate study materials, quizzes, flashcards, and notes using artificial intelligence, and to collaborate in small study groups through our CoWork Sessions feature. We take the responsible use of our platform seriously and require all users to observe the following guidelines.

Compliance with Institutional Policies

Users must not input, upload, or submit any material that violates the policies of their school, college, university, workplace, or instructor. It is your responsibility to understand and comply with your institution's rules regarding the use of AI tools, the recording of educational materials, and the distribution of academic content.

Adherence to Copyright Law

Users must not submit copyrighted material to the Services unless they have obtained explicit permission from the copyright holder or the use is otherwise permitted by law. This includes text, images, lecture materials, textbook content, audio recordings, and any other form of copyrighted work. Preplet processes submitted content through AI to generate study materials, but this does not grant any license to the underlying copyrighted material. See Section 6 (Content and Copyright Policy) and Section 13 (DMCA) for additional detail.

Respecting Privacy

Users are prohibited from submitting sensitive personal information belonging to others, including private conversations, confidential communications, health information, financial data, or any content that would breach privacy laws and regulations in the United States. Do not submit content containing Social Security numbers, medical records, financial account details, passwords, or other sensitive personal data.

Liability

Preplet does not pre-screen user-submitted content. We run automated content safety filters on images and AI interactions through Preplet AI, and we run a client-side profanity filter on direct user-to-user text in CoWork Chat and on the CoWork Board, but we do not review content in advance. We are not liable for content submitted by users that violates institutional policies, copyright law, or privacy regulations. By using the Services, you agree to indemnify and hold harmless Preplet and its operators against any claims, damages, or legal actions arising from your use of the Services or any content you submit.


2. License to Use the Services

Subject to your compliance with these Terms, Preplet grants you a limited, personal, non-exclusive, non-commercial, revocable, and non-transferable license to access and use the Services for your personal educational purposes.

You agree not to:

Subscriptions are for individual use only. Preplet may establish reasonable limits on your use of the Services, including limits on the number of quizzes generated, content processed, Preplet AI calls per minute and per day, or devices used, to prevent abuse or unauthorized access.


3. Account Registration and Age Requirements

Account Creation

To access the Services, you must create an account by providing a display name, email address, and birth month and year, and either signing in through Google or Apple, or creating credentials with an email and password. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. A user under 13 must also provide a parent or guardian email address and parent or guardian phone number during signup; the parent email is used to obtain per-interaction verifiable parental consent as described in the Kid Mode section below, and the parent phone number is used exclusively as a secondary contact channel if the parent email becomes undeliverable.

Minimum Age

Preplet is available to users aged 13 and older through the standard signup flow. Users under 13 may use Preplet through Kid Mode, a parent-in-the-loop experience that complies with the Children's Online Privacy Protection Act ("COPPA"). Kid Mode is available in v3.0 at launch. During signup you will be asked to provide your birth month and year. This is required to create an account and cannot be changed after onboarding except by contacting support. The Kid Mode flow and the per-interaction verifiable parental consent mechanism are described in full in Section 6 of the Privacy Policy.

Kid Mode

A Kid Mode account has access to the same features as an adult Freemium account, including CoWork Sessions. However, any social interaction that discloses information from a Kid Mode account to another user — including inbound and outbound CoWork invitations, direct messages, and session join requests — is held in a pending state and emailed to the parent on file for approval. The parent may approve the interaction for a discrete time window (for Kid Mode ↔ adult interactions: 2 hours, 6 hours, 12 hours, 1 day, 7 days, 30 days, or until revoked; for Kid Mode ↔ Kid Mode interactions: 1 day, 7 days, 30 days, or until revoked) or deny it. Approvals are per-contact and time-bounded. Both parents must independently approve an interaction between two Kid Mode accounts. Pending invitations expire after 7 days if the parent does not act. A parent may revoke any active approval at any time by emailing Preplet from the registered parent email address with the subject "revoke" or "revoke all." If the parent email on file returns hard bounces, the child may continue to use all solo features, any previously-approved CoWork contacts, and any documents or study guides already received through CoWork without interruption; only new CoWork communication actions that require a new parental approval are held until the parent email is re-verified. Preplet sends an SMS to the parent phone number on file with a link to enter a new email address; if the parent does not respond within seven days, the child is directed to ask the parent to email parent@preplet.ai from the new address to rebind it manually. When a Kid Mode user reaches their 13th birthday (calculated from the birth month and year provided at signup), the account automatically transitions out of Kid Mode on next login and prompts the user to add a display name and review the standard Privacy Policy and Terms.

SMS Messaging Program (Kid Mode Account Recovery)

Program name: Preplet Account Recovery.

Program description: When a parent or guardian of a Kid Mode user enrolls a Kid Mode account, Preplet collects the parent's mobile phone number at signup. The phone number is used exclusively as a secondary contact channel to help the parent recover access if the parent email address on file becomes undeliverable. Preplet sends the parent a one-time text message with a secure link to enter a new email address, plus occasional transactional follow-ups related to that recovery flow. The phone number is not used for marketing, advertising, or promotional purposes, and is never shared or sold to third parties.

Message frequency: Infrequent. A parent typically receives a text message only if the parent email on file starts returning delivery failures. Most parents never receive a text message from Preplet.

Message and data rates: Message and data rates may apply. Messaging frequency varies. Charges from your mobile carrier are not controlled by Preplet.

How to opt out: Reply STOP to any Preplet text message at any time to immediately opt out of further text messages. After opting out, you will receive a single confirmation text and no further messages will be sent to that phone number. You may re-enroll at any time by updating the parent phone number on file in your Kid Mode account settings and confirming re-enrollment.

How to get help: Reply HELP to any Preplet text message for support information, or email us at info@preplet.ai.

Supported carriers: All major U.S. mobile carriers are supported. Carriers are not liable for delayed or undelivered messages.

Delivery provider: Preplet delivers text messages through Twilio, a third-party telecommunications provider.

Eligibility: The SMS program is available only within the United States. Only parents and legal guardians enrolling a Kid Mode account, who own or control the mobile phone number provided, should submit a phone number.

Age-Based Data Collection

Data collection practices differ based on age and are described in detail in the Privacy Policy:

When a user reaches a qualifying age based on the birth month and year provided, data collection settings for new activity update automatically. Prior activity from when the user was younger is not retroactively reclassified.

Account Deletion

You may delete your account at any time from the in-app settings. Deleting your account removes your Personal Information from our active databases, subject to limited retention required by law, mandatory reporting obligations, enforcement of these Terms, and tax and accounting requirements. See the Privacy Policy for details.


4. Subscriptions and Payment

Subscription Plans

Preplet offers the following subscription plans. Each is available billed monthly, or billed annually at a discount. An annual plan is a single once-per-year charge; it is marketed in Preplet's upgrade screens as an effective "$X/month billed annually" to make the savings legible, but the actual charge is one annual transaction, not a monthly installment.

Subscription prices are subject to change. Any price changes will be communicated in advance and will take effect at the start of your next billing cycle.

Payment Processing

Subscriptions are purchased and managed on the web at preplet.ai, not through the Apple App Store or Google Play in-app purchase. Payment card information is processed by Stripe, a PCI-DSS Level 1 certified payment processor. For redundancy, if our primary processor is unavailable we may automatically route the transaction to a backup PCI-compliant payment processor. Preplet does not store your full card number — card details are handled directly by our payment processor(s).

Preplet receives transaction confirmation information (subscription type, purchase date, and contact information) but does not receive your full payment card details.

Server-Side Validation

Preplet validates your subscription state server-side and responds to subscription lifecycle events (renewals, refunds, billing grace periods, upgrades, cancellations) through the payment processor's webhooks. Your subscription state on our servers is authoritative; client-side claims of Premium status are not.

Grace Period

If a subscription renewal fails, our payment processor provides a billing grace period during which your access to Premium features, including CoWork hosting and contribution, is preserved. You will be prompted to update your payment method during the grace period. If the issue is not resolved by the end of the grace period, your subscription will lapse and your account will transition to Freemium per Section 5 below.

Refund Policy

Due to the digital nature of the Services, refunds are provided only in cases where a technical malfunction or defect prevents you from accessing or using the features included in your subscription, and we are unable to resolve the issue. To request a refund, contact our support team at info@preplet.ai within 30 days of your purchase with a detailed description of the issue.

Refund requests are also subject to the payment processor's policies. Preplet acts on refund events received through the payment processor's webhooks and will downgrade affected accounts accordingly.

Premium Features

Premium subscribers receive access to the following features in addition to the free tier:

The specific features included in premium subscriptions may change over time. We will communicate any material changes to premium features in advance.

Cancellation

You may cancel your subscription at any time. Cancellations and refunds are managed through your Preplet account or the payment processor's customer portal. Upon cancellation, you will retain access to premium features until the end of your current billing period. After the billing period ends, your account will revert to the Freemium tier as described in Section 5.

Delivery

All Services are delivered digitally. Upon purchase or account creation, you receive immediate access to the applicable features. No physical goods are shipped.


5. Downgrade and Freemium Soft Archive

When your Premium subscription ends (by cancellation, lapse, or refund), your account is not deleted and your content is not destroyed. Preplet uses a soft-archive model so that the path back to Premium is always frictionless:


6. Content and Copyright Policy

Preplet respects the intellectual property rights of all individuals, including educators, authors, and institutions.

Prohibited Actions

The following actions are prohibited on Preplet:

Consequences

Violation of this policy may result in the removal of content, restriction of CoWork access under Section 9, suspension of account access, permanent termination of your account, or legal action.


7. AI-Generated Content

Preplet uses Preplet AI, including its voice features, to generate study materials, quiz questions, flashcards, notes, lecture transcripts, voice-session transcripts, and other educational content. Preplet AI may use third-party AI vendors — including OpenAI, Anthropic, and Google — to process study-guide generation and transcription. You acknowledge and agree that:

Voice Transcripts in Study Room Live Mode (v3.1)

If you use Study Room Live Mode in a future release, you speak directly to Preplet AI and Preplet AI generates a text transcript of the conversation. At the end of each Live Mode session, you choose one of three dispositions: share the transcript with your CoWork group, keep it privately in your CoWork notes for that group, or discard it. Discarded transcripts are not written to our database. Other users in the group do not hear the live audio. Voice transcripts are subject to the same content rules as every other Preplet AI output.


8. User-Generated Content and CoWork Community Guidelines

Preplet's CoWork Sessions feature lets you collaborate with other users in small, invite-only study groups. CoWork includes shared study sessions, a group chat with a Chat button and a Preplet button, a collaborative Board (markdown notes), an activity feed, scheduled events, and Study Room Live Mode voice sessions in a future release. This section governs the content you contribute to CoWork and the behavior expected of every member.

8.1 Your License to Preplet

You retain ownership of the content you create or upload to the Services. By submitting content to CoWork — whether through shared sessions, chat messages, Board edits, voice transcripts, uploaded images and audio, or any other CoWork surface — you grant Preplet a worldwide, non-exclusive, royalty-free license to store, host, reproduce, transmit, display, and process that content solely for the purposes of operating, improving, and providing the Services to you and to the other members of your groups, enforcing these Terms, and complying with our legal obligations. You represent that you have the right to submit the content and that doing so does not violate any third-party rights.

8.2 Visibility Inside a Group

Content you post to a CoWork group is visible to every member of that group as an inherent function of the collaborative product. You should treat anything you post to a CoWork group as visible to all group members. Email addresses are visible only to the group host; non-host members see display names and avatars.

8.3 Community Guidelines — Prohibited Conduct

When using CoWork (or any user-visible surface of the Services, including display names and group names), you agree not to:

8.4 Content Safety Enforcement

Preplet enforces a two-part content safety model described in detail in the Privacy Policy:

8.5 Reports, Blocks, and Host Controls

Every CoWork surface includes a report button on content cards, chat messages, Board regions, and member cards. Reports are delivered to a secure review queue for human review. You may also block another user, which removes you and the blocked user from each other's visibility in shared group content. Group hosts can remove any member at any time, which immediately terminates that member's access to the group.

8.6 Mandatory Reporting of Child Sexual Abuse Material

Under 18 USC 2258A, Preplet is required to report apparent child sexual abuse material (CSAM) to the National Center for Missing and Exploited Children (NCMEC) through the CyberTipline. If we become aware of apparent CSAM on the Services, we will preserve the associated content, account identifiers, and metadata as required by law, freeze the account involved, and file the report. This obligation is not waivable and applies regardless of intent, context, or subscription status.


9. CoWork-Only Strike Ladder

Preplet enforces Community Guidelines violations in CoWork with a four-step CoWork-only strike ladder. The ladder restricts CoWork access only. Solo study features, Talk to Preplet in personal sessions, and all non-CoWork app functionality remain available at every step, including after permanent CoWork loss. The principle is: keep the customer, restrict the feature.

Strikes 1-3 decay after 12 months of clean record. Strike 4 does not decay. Severe violations — including child sexual abuse material, illegal content, targeted harassment, credible threats of violence, and attempts to circumvent safety systems — skip the ladder entirely and result in full account suspension and, where applicable, legal reporting.

Ban state is enforced at the Firestore security rule level, not only in the user interface, and is checked on every write to CoWork chat, Boards, sessions, and related surfaces.

Appeals for Strikes 1-3 are written to the same review queue as reports and are resolved within a reasonable time. While an appeal is pending, the associated strike consequence is paused.


10. Honor Code

Preplet is built to support genuine learning. Our AI-powered tools, including quiz generation, flashcards, notes, Talk to Preplet, and CoWork's collaborative surfaces, are designed to help you study more effectively, not to circumvent the learning process.

The following uses of the Services are strictly prohibited:

Preplet reserves the right to suspend, terminate, or restrict accounts found to be in violation of this Honor Code. We may cooperate with educational institutions investigating academic integrity violations, including sharing relevant account information, CoWork group content, and shared study material when required by law or institutional policy. Honor Code violations inside CoWork may be enforced either through the strike ladder in Section 9 or through direct account-level action, depending on severity.

We believe that effective learning comes from engagement with the material, not from shortcuts. Preplet is a tool to help you understand and retain knowledge, and we ask that all users respect that purpose.


11. Intellectual Property

All content, features, and functionality of the Services, including but not limited to the software, design, text, graphics, logos, and icons, are the property of Preplet and are protected by copyright, trademark, and other intellectual property laws. You retain ownership of the content you create or upload, subject to the license granted in Section 8.1.

AI-generated study materials produced by the Services in response to your input are provided for your personal educational use. You may not commercially distribute, sell, or license AI-generated output from the Services.


12. Disclaimer of Warranties

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. PREPLET DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY DEFECTS WILL BE CORRECTED.

PREPLET DOES NOT WARRANT THE ACCURACY, COMPLETENESS, OR RELIABILITY OF ANY AI-GENERATED CONTENT. YOU ACKNOWLEDGE THAT AI-GENERATED CONTENT MAY CONTAIN ERRORS AND SHOULD NOT BE RELIED UPON AS A SOLE SOURCE OF INFORMATION.

PREPLET DOES NOT WARRANT THE ACCURACY, APPROPRIATENESS, OR LEGALITY OF CONTENT POSTED BY OTHER USERS IN COWORK GROUPS. YOU INTERACT WITH OTHER COWORK MEMBERS AT YOUR OWN RISK AND ARE RESPONSIBLE FOR DECIDING WHICH GROUPS TO JOIN AND WHICH INVITES TO ACCEPT.


13. DMCA Designated Agent

Because CoWork lets users post study content, chat, and Board edits visible to other group members, the Services function as a user-generated content host for the purposes of the Digital Millennium Copyright Act ("DMCA"). Preplet maintains a designated agent for receiving notices of claimed copyright infringement under 17 USC 512(c).

DMCA Designated Agent

Preplet — DMCA Agent

Email: info@preplet.ai

Formal registration of the designated agent with the U.S. Copyright Office is in progress as a pre-launch step and will be reflected in these Terms and in the Privacy Policy when complete.

A valid DMCA notice must include:

Upon receipt of a valid DMCA notice, Preplet will act expeditiously to remove or disable access to the allegedly infringing material and will notify the affected user. Affected users may submit a counter-notice under 17 USC 512(g) containing the elements required by that section.

Preplet maintains a repeat-infringer policy and may terminate the accounts of users who are repeat infringers in appropriate circumstances.


14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PREPLET AND ITS OPERATORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICES, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, EVEN IF PREPLET HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

PREPLET'S TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES SHALL NOT EXCEED THE AMOUNT YOU PAID TO PREPLET IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.


15. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the State of Texas, without regard to its conflict of law provisions. Any disputes arising under these Terms shall be subject to the exclusive jurisdiction of the courts located in the State of Texas.
