Jitterbug

Terms of Service

Last updated: May 4, 2026

These Terms of Service ("Terms") govern your use of the Jitterbug iOS application ("the app") operated by HV Ventures LLC ("we," "us," or "our"). Jitterbug is offered under the Kyvera brand. By downloading, installing, or using the app, you agree to these Terms. If you do not agree, do not use the app.

Use of the app

Jitterbug is a personal caffeine intake tracker. You may use it for your own personal, non-commercial purposes. You agree not to misuse the app, reverse engineer it, copy its code or assets, distribute derivative works, attempt to access systems or data you are not authorized to access, or use the app in any way that violates applicable law.

You must be at least 13 years old to use Jitterbug. If you are between 13 and the age of legal majority in your jurisdiction, you confirm that a parent or legal guardian has reviewed these Terms.

Not medical advice

Jitterbug is a tracking tool, not a medical device. Nothing in the app constitutes medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before making changes to your diet, caffeine intake, sleep schedule, or health regimen, especially if you are pregnant, nursing, take medications that interact with caffeine, or have a heart condition. Do not rely on Jitterbug as a substitute for professional medical guidance.

Subscriptions and purchases

Jitterbug offers the following optional plans to unlock premium features:

Weekly — $3.99/week, auto-renewing, includes a 7-day free trial for new subscribers.
Monthly — $9.99/month, auto-renewing, includes a 7-day free trial for new subscribers.
Lifetime — $19.99 one-time, no renewal, no subscription.

Prices are in US dollars and may vary by region based on App Store pricing. The price shown in the in-app purchase sheet at the time of purchase is the price you pay.

Apple as merchant of record

All purchases are processed by Apple Inc. through the App Store In-App Purchase system. Apple is the merchant of record for your transaction; your billing relationship is with Apple. The App Store's Standard End-User License Agreement (Apple's "Licensed Application End User License Agreement") applies to your download and use of the app, in addition to these Terms. Where these Terms conflict with Apple's standard EULA, Apple's EULA controls.

Free trial

The 7-day free trial is available to new Weekly and Monthly subscribers. Your trial begins the moment you initiate the subscription. If you do not cancel at least 24 hours before the trial ends, your Apple ID payment method will be charged at the selected plan's rate ($3.99/week or $9.99/month) and the subscription will begin auto-renewing. The Lifetime plan does not include a free trial.

Auto-renewal disclosure

Weekly and Monthly subscriptions automatically renew at the end of each billing period unless you cancel at least 24 hours before the renewal date. Your Apple ID account will be charged within 24 hours before the end of the current period. You can manage or cancel your subscription at any time in iOS Settings → your Apple ID → Subscriptions. The Lifetime plan is a single one-time purchase — it does not renew.

How to cancel

To cancel a Weekly or Monthly subscription:

Open the Settings app on your iPhone.
Tap your name at the top to open your Apple ID.
Tap Subscriptions.
Find Jitterbug and tap Cancel Subscription.

Canceling stops future charges. You retain access to premium features through the end of the paid period. We do not offer refunds for partial subscription periods, but Apple may issue refunds at their discretion — contact Apple Support for refund requests at support.apple.com/billing.

Restore Purchases

If you have purchased a subscription or the Lifetime plan from any of your devices, you can restore your premium access on a new or reinstalled device by tapping the "Restore Purchases" button in the app's paywall. This re-checks your Apple ID purchase history and re-applies the entitlement.

Changes to pricing

We may change subscription pricing or introduce new plans at any time. If your existing subscription's price changes, Apple will notify you before the change takes effect, and your renewal will require your confirmation if the price increases. The Lifetime plan price applies to new purchases only — Lifetime owners are not affected by future price changes.

Account deletion

Jitterbug does not require you to create an account. To delete your data, delete the app from your iPhone (this removes all locally stored data). To request deletion of any anonymous analytics events tied to your device's anonymous identifier, email support@kyvera.app. See our Privacy Policy for the full data-deletion path.

Termination and discontinuation

We may suspend or terminate your access to the app if you breach these Terms. We may also discontinue the app or any of its features at any time for any reason, with or without notice. If we discontinue the app entirely:

Active Weekly or Monthly subscriptions will be cancelled by us, and Apple will stop further auto-renewals. Any unused portion of a current paid period is not refundable except where required by law.
Lifetime purchases are made for the app's current functionality at the time of purchase. We will provide reasonable notice (where practical) before discontinuation, but we cannot guarantee perpetual availability of any service in the event of company shutdown, platform changes, or causes beyond our reasonable control.
For at least 30 days after a discontinuation announcement, you will be able to export your local data through the in-app data-export option (where present) before deleting the app.

Intellectual property

All content, design, illustrations, code, and trademarks in Jitterbug are owned by us or our licensors. You are granted a limited, non-exclusive, non-transferable, revocable license to use the app on iOS devices you own or control. This license does not include the right to copy, distribute, modify, sublicense, or create derivative works.

Disclaimer of warranties

Jitterbug is provided "as is" and "as available" without warranties of any kind, express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the app will be error-free, uninterrupted, secure, free of viruses or other harmful components, or that any information presented (including caffeine estimates from the AI scan feature, sleep forecasts, or the drink database) will be accurate or current. Your use of the app is at your own risk.

Limitation of liability

To the maximum extent permitted by law, in no event will we, our affiliates, or our licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages arising from or related to your use of Jitterbug, including but not limited to loss of data, loss of revenue, loss of profits, or harm to health, regardless of the legal theory and even if we have been advised of the possibility of such damages. Our total cumulative liability to you for any claim arising from these Terms or your use of the app shall not exceed the greater of (a) the total amount you paid us in the three months preceding the event giving rise to the claim, or (b) ten US dollars ($10).

Governing law

These Terms are governed by the laws of the State of California and the United States of America, without regard to conflict-of-law principles.

Dispute resolution and arbitration

Please read this section carefully — it affects your legal rights.

You and we agree to resolve any dispute arising out of or related to these Terms or your use of Jitterbug through binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, rather than in court, except as set out below. The arbitration will be conducted in English in San Francisco, California, or by video conference at the arbitrator's discretion. Judgment on the arbitrator's award may be entered in any court of competent jurisdiction.

Small-claims carveout. You may instead bring an individual claim in small-claims court of competent jurisdiction if it qualifies under that court's rules.

Class action waiver. You and we agree to bring claims only in your individual capacity, not as a plaintiff or class member in any purported class, collective, or representative action. The arbitrator may not consolidate more than one person's claims.

30-day opt-out. You may opt out of this arbitration agreement by emailing support@kyvera.app within 30 days of first agreeing to these Terms with the subject line "Arbitration Opt-Out" and including your device's anonymous identifier (visible in the app's Settings → About). If you opt out, you are not bound by this arbitration section, but the rest of these Terms still apply.

Changes to these terms

We may update these Terms at any time. When we make material changes, we will update the "Last updated" date at the top of this page and surface the change inside the app on the next launch with at least 14 days' notice for material changes that affect your subscription or rights. Continued use of the app after the effective date of a change constitutes your acceptance of the revised Terms.

Severability

If any provision of these Terms is held to be unenforceable, that provision will be severed and the remaining provisions will remain in full force. A failure or delay by us to enforce any right under these Terms is not a waiver of that right.
