Terms of Service
Effective date: November 5, 2026 · Updated November 8, 2026
1. The agreement
Dart Keeper is made by Vexcom LLC, a California limited liability company in Vacaville, California ("Vexcom," "we," "us"). Dart Keeper is a business name of Vexcom LLC.
These terms cover:
- the Dart Keeper website at dartkeeper.net;
- the web app at dartkeeper.net/play;
- the Dart Keeper apps for iPhone, iPad and Android;
- the servers that back up players and run leagues.
Together we call all of that "Dart Keeper."
By using Dart Keeper, you agree to these terms and to our Privacy Policy. If you don't agree, please don't use Dart Keeper.
2. Who can use Dart Keeper
You must be at least 13 years old to use Dart Keeper. If you are under 18, you need a parent's or guardian's permission. You must be 18 or older to buy a subscription.
You may not use Dart Keeper if:
- the law where you live forbids it; or
- we have previously removed you from it.
3. Players, email and sign-in
- No account needed to keep score. The players and games you enter are stored on your phone or tablet.
- Your email address (optional). It does three things:
- Dart Keeper is not a backup service. It's built to work offline and to send finished games to our servers when it can. But a device that's lost, reset or offline for a long time can lose games that were never sent. Back up with your email, and keep your device's software up to date.
4. What Dart Keeper does — and doesn't
Dart Keeper keeps score for darts, including:
- 301, 501, Cricket, Fat 6 and other games;
- league nights, team standings and reports.
We keep improving it, which means features will change. We may add, change or remove features at any time.
We work hard to keep Dart Keeper running. But it depends on:
- devices and networks;
- app stores;
- services run by other companies.
We can't promise it will always be available or error-free, or that every game will reach our servers.
5. Entering other people
Dart Keeper is often run on a shared tablet. One person types in everyone's names and sometimes their email addresses. If you add a player:
- You need their OK. You confirm the player agreed to be added under that name. If you add their email, you confirm they agreed to receive Dart Keeper's league and backup messages there.
- No one under 13. Don't add a child under 13, or a child's email address.
- Use real names or names they chose. Don't add a name meant to mock, harass or impersonate someone.
Shared tablets. If you set up a phone or tablet for others to score on, you're responsible for how it's used under these terms.
Being removed. A player who wants their name or email removed can:
- ask their league head, who can remove or merge names in the league; or
- write to privacy@vexcomllc.com, and we'll remove or anonymize them, even if they never used Dart Keeper themselves.
6. Leagues
- Starting a league. Any player can start a league. The person who starts it is its head. Each league name is unique and is confirmed by the head's email.
- Joining. People join a league with its code. Anyone holding the code can join, so share it only with your league.
- What the head can do. The head runs the league. They can:
- add, remove and merge names;
- approve moves between teams;
- fix claims;
- set the league's weekly night;
- receive the night's report.
- The league isn't one person's. It doesn't end when its creator stops playing.
- The head role can be handed to another member.
- If a head leaves and nobody can reach them, another member can take over the head role as the app allows.
- If people disagree about who controls a league, we may ask for information. We then decide, acting reasonably, and our decision is final.
- League data is for the league.
- The roster, results, stats and members' emails are there to run the league.
- Heads and members may not use them to sell, advertise or solicit, or share them outside the league.
- Other members' emails stay private. The head's email is visible to members so they can reach the head.
- League nights.
- Games count toward the league when League is on for that night. A league's scheduled night turns it on and off automatically on every league device.
- Games scored with League off are kept and can be added later by someone who chooses to.
- The head and the league decide what counts. Vexcom doesn't.
7. Scores, stats and league disputes
- Scores are what players enter. Scores, standings, averages and reports come from what players tap in. If an entry is wrong, the result is wrong. Use Undo, or ask your head to fix it.
- Vexcom is not part of your league. We aren't responsible for:
- Release. If you have a dispute with another player, team or league head, you release Vexcom from any claim connected to it. If you are a California resident, you waive California Civil Code §1542 for those disputes. That section says: "A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party."
8. League emails
When a league is running, Dart Keeper e-mails:
- the night's report to the people on its roster;
- notices about joining or being removed.
You can change which reports you get, or stop them, from the links at the bottom of any league email. We don't share players' email addresses with advertisers or partners.
9. Your content
"Your content" means everything you put into Dart Keeper:
- player and team names;
- scores, stats and games;
- league settings.
You own your content. You give Vexcom a worldwide, royalty-free license to host, store, copy, display and send your content, only as needed to:
- run Dart Keeper, including showing league results to the league;
- back it up and restore it for you;
- keep Dart Keeper safe and fix problems; and
- improve Dart Keeper.
This license ends when your content is deleted, except for copies already in other members' league history (see section 15).
You confirm you have the right to enter your content, including other people's names and emails (section 5).
Feedback. If you send us ideas or suggestions, we may use them freely.
10. Community rules
When you use Dart Keeper, don't:
- use player, team or league names that are hateful, sexual, harassing or meant to mock a real person;
- impersonate someone, or claim a league or name that isn't yours;
- add people without their OK, or use league emails for anything but the league;
- tamper with scores, standings or other leagues;
- copy, scrape or bulk-download data from Dart Keeper, or use it to build a competing product;
- reverse engineer the apps or our servers, get around their protections, or overload them. This doesn't limit any rights you have under an open-source license.
Report and block. Tap ⚑ Report on a player's card, or the report button beside the league list, to report a name or a league. Report & Block also hides it on your device. You can also email hello@dartkeeper.net. New player, team and league names are checked against a word filter, and a name that fails is refused. We review reports and may:
- remove or rename content;
- limit features; or
- remove players or leagues that break these rules.
We don't watch every game, and we aren't responsible for what other users enter. But we act on what's reported to us.
Under-18 removal. If you're a California resident under 18, you can remove content you posted, or ask us to, at hello@dartkeeper.net.
11. Copyright complaints
If you believe content in Dart Keeper infringes your copyright, send a notice to our designated agent. Include:
- your contact details;
- the work;
- where the content is in Dart Keeper;
- a good-faith statement; and
- a statement under penalty of perjury that you are authorized.
Our designated agent: Copyright Agent, Vexcom LLC, 475 Edwin Dr, Vacaville, CA 95687-5243 · hello@vexcomllc.com · (707) 689-6619. (U.S. Copyright Office registration DMCA-1085282.)
We may remove repeat infringers.
12. Our property
Dart Keeper, its software, design, art, dartboard, game rules pages and the names Dart Keeper and Vexcom belong to Vexcom or our licensors. Dart Keeper™ is a trademark of Vexcom LLC.
These terms give you a personal, non-transferable right to use Dart Keeper for your own games and leagues. They don't give you any other rights in our property.
Dart Keeper includes open-source software, which is used under its own licenses. Nothing in these terms limits your rights under those licenses.
13. Paid features (when offered)
What's free. Dart Keeper is free today. If we offer a subscription, these things stay free for everyone:
- keeping score;
- playing in a league;
- joining a league; and
- finishing a season that has already started.
What a subscription is for. A subscription may be needed to create a league or start a new season, or for other features we describe in the app before you buy. A subscription belongs to the person who bought it. It covers the leagues and seasons that person creates or starts. Other members keep playing for free.
If a subscription ends, the league and its history aren't deleted. Games, standings and reports already recorded stay. Starting the next season may need a subscription from any member.
Billing.
- Paid subscriptions are sold through the Apple App Store or Google Play, and billed by Apple or Google under their terms.
- Before you buy, the app shows the price, the billing period and what the subscription includes.
- Subscriptions renew automatically at the end of each period, at the then-current price, until you cancel.
- You can cancel any time in your Apple ID or Google Play settings. The app links there.
- Cancel at least 24 hours before the renewal date to avoid the next charge.
- When you cancel, you keep paid features until the end of the period you paid for.
Price changes. We'll tell you before a price increase applies to your subscription, and you can cancel before it takes effect.
Refunds. Refunds are handled by Apple or Google under their policies. We don't give partial refunds for unused time, except where the law requires it.
Special arrangements. We may give some players or leagues paid features for free, or at a different price, at our discretion. That doesn't change these terms for anyone else.
Renewal reminders. For yearly plans, we'll send a reminder before each renewal, as California law requires.
14. Your data and privacy
Our Privacy Policy explains what Dart Keeper collects and why. That includes:
- the game records sent to our servers;
- the city and network that your internet address maps to;
- league emails.
15. Ending your use
You can stop any time. To delete your account, go to Add/Manage Players › Backup & Share › Delete account. If you've entered an email address, we send a 6-digit code to it first. You can also follow the steps at dartkeeper.net/delete or write to privacy@vexcomllc.com. Games you played in a league stay in that league's history so everyone else's results still add up, but your name in them becomes "Former player" and a number.
We can suspend or end your use. We may do this if:
- you break these terms;
- the law requires it; or
- continuing would harm other users or Vexcom.
We'll tell you why when we reasonably can. We may also stop offering Dart Keeper altogether. If we do, we'll give reasonable notice and a way to keep your data where possible.
Sections 5–7, 9 (license already used), 12 and 16–21 continue after these terms end.
16. Disclaimers
Dart Keeper is provided "as is" and "as available." To the fullest extent the law allows, Vexcom disclaims all warranties, express or implied. That includes warranties of:
- merchantability;
- fitness for a particular purpose;
- accuracy; and
- non-infringement.
We don't promise that scores, statistics, standings or reports are accurate or complete.
Some places don't allow these disclaimers, so some of them may not apply to you.
17. Limits on our liability
To the fullest extent the law allows:
- Vexcom is not liable for indirect, incidental, special, consequential or punitive damages. That includes lost money, lost profits, lost data, or losses from league prizes, dues, pots or bets.
- Vexcom's total liability for all claims relating to Dart Keeper is limited to the greater of:
- what you paid us for Dart Keeper in the 12 months before the claim; or
- $50.
These limits don't apply to liability that can't be limited by law, such as for fraud, or for death or personal injury caused by our gross negligence or willful misconduct.
18. Indemnity
If someone brings a claim against Vexcom arising from any of the following, you will cover Vexcom's reasonable losses and costs from that claim:
- your content;
- people you added without their OK;
- your league's decisions;
- your breaking these terms; or
- your breaking the law.
This doesn't apply to the extent the claim was caused by Vexcom.
19. Resolving disputes
Talk to us first. Before starting a formal claim, email hello@vexcomllc.com with your name, the problem and what you want. Both sides will try in good faith to resolve it for 60 days.
Courts. If we can't resolve it, disputes go to the state or federal courts in Solano County, California, and you and Vexcom agree to their jurisdiction. Either side may instead bring an individual claim in small-claims court.
20. Changes to these terms
We may update these terms. If a change is significant, we'll tell you in the app or by email at least 30 days before it takes effect, unless the change is required by law or fixes a safety problem. If you keep using Dart Keeper after a change takes effect, you accept it.
21. Everything else
- Governing law. California law governs these terms, apart from its conflict-of-law rules.
- Entire agreement. These terms and the Privacy Policy are the whole agreement between you and Vexcom about Dart Keeper.
- Severability. If part of these terms can't be enforced, the rest still applies.
- No waiver. Not enforcing a term right away doesn't waive it.
- Assignment. You can't transfer these terms. We may transfer them with our business.
- Events beyond our control. We aren't responsible for delays or failures caused by events beyond our reasonable control.
- California users. Under California Civil Code §1789.3, you may contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by phone at (800) 952-5210.
22. App stores
If you got Dart Keeper from the Apple App Store or Google Play, these terms are between you and Vexcom only, not Apple or Google. The store's own terms also apply.
For the Apple App Store:
- Apple has no obligation to provide maintenance or support for Dart Keeper.
- If the app fails to meet any warranty, you may notify Apple, and Apple will refund the purchase price (if any). Apple has no other warranty obligation.
- Vexcom, not Apple, is responsible for:
- claims about the app, including product liability claims;
- claims that it fails to meet legal requirements;
- consumer-protection claims; and
- claims that the app infringes someone's intellectual property.
- You confirm that you aren't in a country under U.S. embargo, and aren't on a U.S. list of restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them.
