Flash is a spaced-repetition flashcard service at flashmemorize.com, run by Rumbo Software LLC, 7901 4th St N, Ste 300, St. Petersburg, FL 33702, United States ("we", "us"). These terms are the agreement between you and us when you use Flash.
The Free plan includes unlimited cards with the full scheduler, study on the website, through AI assistants over MCP and in the Flash app, and import and export, with no time limit. On the Free plan, up to 1,000 active cards (cards not archived or deleted) sync between your account, your devices and your AI assistants, the oldest first; a newer card stays where it was made, on the device or in the account, and keeps working there. The app also includes a small amount of voice study each calendar month, shown as a share used. Flash Pro ($19.99 a year in the United States, billed yearly, renewing automatically until cancelled; the price shown by the App Store or Google Play may differ in your country) syncs every card between your devices, the website and your AI assistants, backs them up, and includes voice study in the app without the monthly limit, subject to fair-use limits that keep the service running for everyone. When a subscription ends, the 1,000 oldest active cards keep syncing; each newer card stays on every device that holds it and in your account, and each copy is studied separately. Nothing is deleted. If the price of Flash Pro changes, it changes for new subscriptions; an active subscription keeps its price for as long as it renews. Subscriptions from before the yearly plan continue on their original terms until cancelled. Complimentary accounts are granted at our discretion. We may change the number of cards that sync for free or the free voice study, with notice as described below.
You can export your full collection (Anki .apkg or CSV) at any time, on any plan. Studying cards you already have is never paywalled where they live: on the website and through your AI for your account's decks, and in the app for the decks on that device.
You keep every right you have in what you put in Flash. You let us store, copy, process and show it only as needed to run Flash for you, including sending it to the providers named in the privacy policy when you use a feature that needs them, and to show what you share to the people you share it with.
Card generation, the grading of spoken answers in voice study, and the answers to your questions about a card are written by AI models that other companies run (the privacy policy names them). What they write can be wrong or incomplete: check generated cards before you keep them, and check what matters against your course material. Flash is a study aid, not professional advice.
On the website, Flash Pro is sold by Stripe, through its Link service, as the merchant of record: the seller who bills you and handles sales tax. In the app it is sold by Apple or Google. The one that sells it to you bills you, sends your receipt, and handles refunds and billing disputes under its own terms and the consumer law of your country. Flash Pro renews every year until you cancel. Cancel any time from Settings, in Link, or in your App Store or Google Play subscriptions; Flash Pro stays active until the end of the year you paid for.
Flash is for studying. Your decks, cards, and any images or audio you upload are private to your account unless you share them: a share link shows a deck to anyone holding the URL, and publishing to the Community lists it publicly under your display name after we review it. Shared decks may be copied by other users; you keep whatever rights you have in the content and grant other users the right to copy and study it. You must have the right to share anything you share. Whether private or shared, you agree not to use the service to store or transmit:
We may remove content and suspend or terminate accounts that violate these terms, with or without notice depending on severity, and we cooperate with lawful requests from law enforcement. Repeat infringers are terminated. When we remove something of yours or limit your account, we tell you what we did and why, unless the law or someone's safety prevents it, and you can reply to ask us to look again.
If you believe material stored on Flash infringes your copyright, send a notice to our designated agent at [email protected] with: your contact details; a description of the copyrighted work; enough information for us to locate the material (the account email or user id, if known); a statement that you have a good-faith belief the use is not authorized; a statement, under penalty of perjury, that the notice is accurate and you are the rights holder or authorized to act for them; and your physical or electronic signature. We act on valid notices promptly and notify the affected account, which may file a counter-notice under 17 U.S.C. § 512(g).
To report any other violation of these terms, email [email protected] with as much detail as you can. We review every report.
You must be at least 13 years old to use Flash. If the law where you live asks for a parent's or guardian's permission at your age, you need it to use Flash. You are responsible for keeping your credentials safe and for everything done under your account. You can stop using Flash at any time, and delete your account yourself in Settings › Delete account.
We may change these terms as Flash changes. We announce a material change at least 30 days before it takes effect, by email and in Flash, showing what changes. If you keep using Flash after that, the new terms apply to you; if you don't accept them, you can close your account before they take effect.
We do our best to keep Flash running and your data safe (including off-site backups), but you should keep exports of anything you can't afford to lose. Flash is provided as it is and as available, without warranties beyond those the law requires. As far as the law allows, we are not liable for indirect or consequential losses, and our total liability to you is limited to what you paid for Flash in the 12 months before the claim, or US$100 if that is more. Nothing in these terms excludes or limits liability that the law does not allow to be excluded or limited, such as for fraud, for harm caused on purpose or by gross negligence, or for death or personal injury caused by negligence.
If you use Flash as a consumer, nothing in these terms takes away the rights that the law of the country where you live gives you and that a contract cannot set aside.
These terms are governed by the laws of the State of Florida, United States, and disputes go to the state or federal courts in Florida. If you are a consumer, the mandatory consumer law of the country where you live still applies, and you may also bring a claim in the courts where you live. There is no arbitration agreement in these terms.
You may not use Flash where United States or other applicable sanctions or export laws forbid it, or if you are on a United States government list of restricted parties.
These terms are written in English and in French, and both versions are equally binding. If they differ, the reading more favorable to you applies.
