Terms of service

1. Acceptance of terms

By creating an account or using Voltra you confirm that you are at least 16 years old and that you accept these Terms. If you do not agree to these Terms you must not use the app. If you are below the age at which you can enter into a binding contract where you live, a parent or legal guardian must agree on your behalf where local law permits this.

2. Description of service

Voltra is a progressive web application for tracking workouts, training programs, and fitness progress. Features are available on a free tier, a paid subscription, or a 14-day trial with Progress access and the creation limits described in section 5. Changes to the service are covered by section 10, and account suspension or closure by section 12.

3. Accounts

You are responsible for maintaining the confidentiality of your account credentials and taking reasonable steps to secure your account. Please notify us promptly if you suspect unauthorised use. This does not make you responsible for activity caused by our failure to meet our legal or contractual obligations.

4. Subscriptions and billing

Paid subscriptions are billed on a monthly or annual basis via Stripe. Your subscription renews automatically at the end of each billing period unless you cancel before the renewal date. Cancellation takes effect at the end of the current billing period — you retain access to paid features until then. To cancel renewal, open Settings → Account → Manage Subscription and follow the cancellation steps in the Stripe customer portal. If you cannot access your account or the portal, you may also cancel by notifying us. Uninstalling the app or signing out does not cancel a subscription.

The applicable currency, total price including applicable taxes, billing interval, and renewal terms will be shown before you confirm your purchase. Price changes apply only to a future renewal, with at least 30 days' advance notice by email. You may cancel renewal before the new price takes effect. A price change does not alter a billing period you have already paid for.

Failed payments may lead to loss of paid access after payment retries. A downgrade preserves existing workout content but restricts creation to the free-tier limits and removes Progress access. Cancellation of renewal is separate from withdrawal or other refund rights, described in section 11.

5. Free trial

New accounts automatically receive a 14-day trial with full Progress access. The trial has the same creation limits as the free tier: 2 custom exercises, 1 training program, and 8 exercises per program. Paid subscriptions allow unlimited custom exercises and programs, with up to 20 exercises per program. No payment method is required to start the trial. At the end of the trial period your account is automatically downgraded to the free tier unless you subscribe. Existing data is preserved on downgrade, but creation of new items beyond the free-tier limits is blocked. Progress access ends when the trial expires unless you subscribe. The trial does not automatically become a paid subscription, and you will not be charged unless you purchase one.

6. Acceptable use

You agree not to:

• Use Voltra for any unlawful purpose
• Attempt to gain unauthorised access to other users' data or any part of our systems
• Reverse-engineer, decompile, or disassemble any part of the app, except where applicable law permits this
• Transmit any harmful, offensive, or disruptive content via the app
• Use automated means to access other users' data, bypass access controls, or disrupt the service. This does not limit your statutory rights to access or receive your own data.

7. Intellectual property

Voltra and its content, features, and functionality are owned by us and protected by applicable intellectual property laws. You retain any intellectual property rights in workout content you create. You grant us a limited licence to store and process that content solely to provide the service to you. Personal data is handled as described in our Privacy Policy; this licence does not replace our data-protection obligations or your privacy rights.

8. Disclaimers

Voltra is a workout logging tool. Its calculations, statistics, and training references are informational and do not replace medical advice or individual guidance from a qualified professional. Choose exercises appropriate to your health and abilities, and seek professional advice when needed. We do not guarantee a particular training result or uninterrupted, error-free operation. This does not exclude statutory guarantees, our obligation to supply the service as agreed, or liability that cannot lawfully be excluded.

9. Limitation of liability

Nothing in these Terms excludes or limits liability for fraud, wilful misconduct, death or personal injury caused by our negligence, or any other liability that applicable law does not allow us to exclude or limit. Your mandatory consumer and data-protection rights remain unaffected, including when you use the free tier or trial. Subject to those protections, we are not responsible for losses that were not reasonably foreseeable when you entered into this agreement, or business losses arising from use of this service for personal training.

10. Changes to the service and these Terms

We may make changes for valid reasons, such as legal requirements, security, or improvements to the service. For material changes to these Terms or changes that negatively affect your access to or use of the service, we will explain the change and its effective date by email at least 30 days in advance. Urgent legal or security changes may require shorter notice; we will explain them as soon as reasonably possible. Price changes follow section 4.

If you do not agree to a material change, you may stop using the service and cancel your subscription before it takes effect. Where a change materially reduces your paid service, you may terminate the affected subscription and receive a proportionate refund for the unused prepaid period. We will obtain agreement where required by law; continued use alone does not waive your mandatory rights. We will update the date above when these Terms change.

11. Withdrawal and refunds

If you are an EU or EEA consumer, you generally have 14 days from entering into a paid service contract to withdraw without giving a reason. To withdraw, notify us with a clear statement before the deadline, identifying your account and purchase. You may use this wording, but do not have to: "I withdraw from my Voltra subscription purchased on [date]. My account email is [email]. My name and address are [details]."

We will reimburse payments due on withdrawal within 14 days of receiving your notice, using the original payment method unless agreed otherwise, without a refund fee. If you expressly request that service begins during the withdrawal period, a proportionate charge may apply only where the law permits and the required information and consent have been provided. Using Voltra does not by itself waive your withdrawal rights.

Outside statutory withdrawal, cancelling renewal normally leaves access active until the end of the paid period. Any rights to repair, price reduction, termination, or a refund for a defective or unavailable service remain unaffected. Consumers elsewhere retain the cancellation and refund rights granted by local law.

12. Suspension and account closure

You may request account deletion in Settings → Danger Zone. Deletion cancels an active subscription and removes your Voltra account and workout content through the deletion process. It is different from cancelling renewal, which retains your account and paid access until the end of the billing period. Account deletion does not itself request a refund or exercise a right of withdrawal; contact us for those requests. Save any content you need before deletion, and consult the Privacy Policy for data-retention information and your data rights.

We may restrict or suspend access where reasonably necessary to address a serious breach of these Terms, a security threat, or a legal requirement. Where lawful and practicable, we will explain the reason and give you an opportunity to resolve the issue or challenge the decision before closing your account. Immediate action may be necessary to protect users or comply with law.

If we permanently discontinue the service or close your account for reasons unrelated to a breach by you, we will give reasonable advance notice, an opportunity to retrieve your content, and a proportionate refund for unused prepaid service. Legal or security restrictions may limit advance notice or access. Any additional remedies required by law remain available.

13. Governing law and disputes

Applicable law determines the law governing these Terms. Consumers retain the mandatory protections applicable in their country of residence. Nothing in these Terms restricts your right to bring a claim in a court available to you under applicable law or to contact a consumer-protection authority. Please contact us first if you would like us to try to resolve a complaint; this is not a condition of exercising your legal rights.
