These Terms constitute a legally binding agreement between you and Booklet ("we", "us", or "our"), the owner and operator of the Booklet mobile application and website. Your continued use of the App following any updates to these Terms constitutes acceptance of the revised version.
Booklet is a study platform designed to help you create, manage, and study flashcards using spaced repetition algorithms. We provide the infrastructure for you to organize your learning materials, track your progress, and improve long-term retention.
The App may be updated over time to include additional features or modify existing functionality. Material changes to the App's core features (including significant alterations to service scope, pricing, or core functionality) will be communicated via in-app notice or email at least 30 days in advance.
To access certain features of the App, you may be required to create an account.

You must be at least 13 years of age (or the applicable minimum age in your country, such as 16 in certain EEA member states) to create an account. By creating an account, you represent that you meet this requirement.

Your Ownership
You retain full ownership of all flashcards, decks, and other materials you create in the App ("User Content").
License to Booklet
By using the App, you grant Booklet a non-exclusive, worldwide, royalty-free license to store, process, display, and synchronize your User Content solely for the purpose of providing the Service to you. This license terminates when you delete the content or close your account.

If you choose to make decks publicly available within the App, you additionally grant Booklet and other users a limited, non-sublicensable license to access, view, and study that content solely for personal, non-commercial use within the App's features. Users may not redistribute, sell, or create derivative works from public content outside of the App. While we take measures to enforce these restrictions, you acknowledge that Booklet is not responsible for any unauthorized redistribution of public content by third parties. This public license terminates when you remove public access to the deck or delete your account.

All code, design, trademarks, logos, and original content of the App (excluding User Content) are the exclusive intellectual property of Booklet and are protected by copyright, trademark, and other applicable laws.

THE APP AND ALL SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMISSIBLE UNDER APPLICABLE LAW, BOOKLET DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE.
WITHOUT LIMITING THE FOREGOING, BOOKLET MAKES NO WARRANTY, REPRESENTATION, OR GUARANTEE AND EXPRESSLY DISCLAIMS ANY RESPONSIBILITY FOR:
YOUR USE OF THE APP IS AT YOUR SOLE RISK. YOU ARE SOLELY RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE, LOSS OF DATA, OR LOSS OF BUSINESS OR EDUCATIONAL PROGRESS THAT RESULTS FROM THE USE OF THE APP.
YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT BOOKLET ASSUMES NO MATERIAL, MONETARY, OR FINANCIAL LIABILITY WHATSOEVER, AND SHALL NOT BE RESPONSIBLE OR LIABLE UNDER ANY CIRCUMSTANCES FOR ANY DAMAGE, COST, EXPENSE, OR LOSS ENCOUNTERED BY YOU OR ANY THIRD PARTY. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL BOOKLET, ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUES, BUSINESS, OPPORTUNITY, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, REGARDLESS OF THE THEORY OF LIABILITY (INCLUDING CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY, OR OTHERWISE), EVEN IF BOOKLET HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, RESULTING FROM:
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL AGGREGATE LIABILITY OF BOOKLET FOR ALL CLAIMS ARISING UNDER, OUT OF, OR RELATED TO THESE TERMS OR THE APP SHALL BE ZERO U.S. DOLLARS (U.S. $0.00). YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY DISPUTE WITH BOOKLET OR ANY DISSATISFACTION WITH THE SERVICE IS TO DISCONTINUE USING THE APP.
THE LIMITATIONS AND EXCLUSIONS OF LIABILITY IN THIS SECTION APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OR EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU. IN SUCH JURISDICTIONS, LIABILITY IS LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.
You agree to indemnify, defend, and hold harmless Booklet, its affiliates, and their respective officers, directors, employees, and agents from and against any and all claims, liabilities, damages, losses, and expenses, including reasonable legal and accounting fees, arising out of or in any way connected with:
Booklet shall not be liable for any delay or failure to perform resulting from causes outside its reasonable control that are unforeseeable and unavoidable, including, but not limited to, acts of God, war, terrorism, riots, embargos, acts of civil or military authorities, fire, floods, accidents, strikes, or shortages of transportation facilities, fuel, energy, labor, or materials, or failures of third-party service providers (including cloud hosting providers).
These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to conflict of law provisions.
CLASS ACTION WAIVER: TO THE EXTENT PERMITTED BY LAW, YOU AND BOOKLET AGREE THAT ANY DISPUTE RESOLUTION PROCEEDINGS WILL BE CONDUCTED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. YOU WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION AS A REPRESENTATIVE OR MEMBER.
Any disputes arising under these Terms shall first be attempted to be resolved through good-faith negotiation. If unresolved within 30 days, disputes shall be submitted to binding arbitration under the rules of the American Arbitration Association, except that either party may seek injunctive relief in a court of competent jurisdiction. For users residing in the European Union or other jurisdictions where local law grants a right to resolve disputes in local courts or through specific Alternative Dispute Resolution (ADR) mechanisms, those laws shall apply notwithstanding this section.
Severability: If any provision of these Terms is held to be unenforceable or invalid, such provision will be changed and interpreted to accomplish the objectives of such provision to the greatest extent possible under applicable law and the remaining provisions will continue in full force and effect.
Entire Agreement: These Terms, along with our Privacy Policy, constitute the entire agreement between you and Booklet regarding the use of the App and supersede all prior written or oral agreements.
No Waiver: Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights.
