Terms of Service — Suzztain

Effective date: August 31, 2026

Suzztain (“the app”) is a mobile application published by Zero Jump Apps, LLC (“we”, “us”, “the developer”). These Terms of Service (“the Terms”) are the agreement between you and the developer covering your use of the app.

By installing or using Suzztain, you agree to these Terms. If you do not agree to them, do not use the app.

Contact: support@zerojumpapps.com

1. Summary

Suzztain is a single-exercise timer with rep counting, a training history, and a muscle map, and it runs entirely on your device. There is no account, no server, and no internet transmission — the app does not even hold the Android internet permission. Your training log is yours, we never see it, and we cannot recover it for you if it is lost.

The four things that matter most in this agreement: exercise carries risk and this app is not medical advice (section 7), the muscle map and the recovery reminder are estimates rather than physiology (section 8), timers depend on your device and may be delayed by it (section 9), and you must keep your own backups (section 5).

2. The licence we grant you

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Suzztain on devices you own or control, for your own personal, non-commercial purposes.

This is a licence to use the app, not a sale of it. All rights not expressly granted to you are retained by the developer.

3. What you may not do

You agree not to:

• Copy, sell, rent, lease, sublicense, or otherwise distribute the app itself
• Reverse engineer, decompile, or disassemble the app, or attempt to derive its source code, except to the extent applicable law expressly permits this despite this restriction
• Modify the app or create derivative works based on it
• Remove or obscure any copyright, trademark, or other proprietary notice
• Use the app for any unlawful purpose

4. Your training log is yours

Everything you record in Suzztain — your sessions, notes, tags, custom exercises and records — belongs to you. The developer claims no ownership of it and no licence to it.

Because the app has no backend, we never receive your entries and have no ability to read, moderate, retrieve, or restore them. What the app stores and where is described in the Suzztain Privacy Policy.

5. Data loss — read this

Suzztain stores your training log in the app’s private storage on your device and nowhere else. There is no cloud copy. This is a deliberate privacy decision, and it has a direct consequence you must accept in order to use the app:

If you uninstall the app, use “Delete all data” in Settings, clear its data, lose your device, damage it, or if its storage fails, your training log is permanently gone.

We cannot recover it. There is no copy anywhere for us to restore from, no account to sign back into, and no support request that can undo it. “Delete all data” asks twice and then does exactly what it says.

You are responsible for maintaining your own backups using the app’s export feature, and for keeping those exports somewhere you will still have access to them.

6. Exports are not encrypted

The app’s CSV export and JSON backup are plain, human-readable files. They are not encrypted and not password-protected.

Once you export a file, it leaves the app’s protected storage and you are solely responsible for it — where you save it, who you send it to, and whether it stays private. If you place it in cloud storage, email it, or share it, it becomes subject to that service’s practices and outside our control.

Restoring merges rather than replacing: entries already present are skipped and nothing already in the app is deleted by a restore. Personal records are recomputed from the sessions that are actually present, so a hand-edited backup cannot fabricate a record.

7. Not medical or fitness advice, and exercise carries risk

Suzztain is a timer and a record-keeping tool. It is not a medical device, not a diagnostic tool, not a coach, and not a substitute for professional care or qualified instruction.

Nothing in the app — including any timer, count, statistic, chart, streak, personal record, muscle colour, load figure, or recovery notification — constitutes medical, physiotherapeutic, nutritional, or training advice, and none of it should be relied on as such. The app does not know your age, health, injuries, medication, pregnancy, experience, or technique, and it makes no claim that any exercise, duration, intensity, or schedule is safe or appropriate for you.

Physical exercise carries inherent risk of injury or death, including from overexertion, poor form, pre-existing conditions, and exercising without adequate rest or supervision. You use the app, and choose what to do while using it, entirely at your own risk.

Consult a qualified physician or health professional before beginning or changing an exercise programme, and stop immediately and seek medical attention if you experience pain, dizziness, breathlessness, chest discomfort, or any other warning sign. Never disregard or delay professional advice because of something in this app. Do not use the app while driving or doing anything else that requires your attention.

8. The muscle map and the recovery reminder are estimates

The body map, the load figures behind it, and the “recovery ready” notification are produced by a simple model: recorded work, weighted by which muscles an exercise is mapped to, decaying over time at a rate you can change in Settings. Its constants are uncalibrated starting points, not measurements.

They describe what you recorded in this app, not the physiological state of your body. A muscle shown as recovered may not be. A muscle shown as heavily worked may not be. Work you did not record does not exist as far as the app is concerned. Do not use these figures to decide whether you are fit to train, whether an injury has healed, or how hard to push.

9. Timers, alarms, and notifications

The app computes elapsed time from the system clock rather than by counting, so a session’s recorded duration stays correct even if the app is closed or stopped. Delivery of an alarm or a notification, however, depends on your device: battery optimisation, Doze, manufacturer power management, Do Not Disturb, a revoked notification permission, a device that is switched off, or a manual change to the system clock can delay or suppress it.

Suzztain therefore does not guarantee that a timer will alert you at a particular moment, and you must not rely on it where a missed or late alert could cause harm — including any medical, occupational, or safety-critical purpose. It is a training timer, and that is all it is.

10. Purchase, price, and refunds

Suzztain is sold as a one-time purchase through Google Play. There are no subscriptions, no in-app purchases, no advertising, and no feature behind a second payment. The price is set at the store and may change for future purchasers; a change does not entitle you to a refund of an earlier purchase.

Payment, billing, and refunds are handled by Google Play under its own terms and refund policy. We are not able to process a payment or issue a refund ourselves. Nothing in this section limits any statutory refund or consumer right you have under applicable law.

11. No warranty

The app is provided “as is” and “as available”, without warranty of any kind.

To the fullest extent permitted by law, the developer disclaims all warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the app will be uninterrupted or error-free, that it will work on every device or operating system version, that alarms or notifications will always be delivered on time, that exports or restores will always succeed, or that data will not be lost.

12. Limitation of liability

To the fullest extent permitted by law, the developer will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any personal injury, loss of training data, loss of exports, disclosure of an exported file, missed or late notification, or lost progress, arising out of or connected with your use of or inability to use the app, however caused and on any theory of liability.

Where liability cannot be excluded, the developer’s total aggregate liability to you for all claims relating to the app is limited to the greater of the amount you paid for the app or USD $10.00.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. Where that is the case, the exclusions and limitations above apply only to the extent permitted. Nothing here excludes liability for death or personal injury caused by negligence, for fraud or wilful misconduct (dolo), or for anything else that cannot lawfully be excluded.

Under the law of Puerto Rico, an advance waiver of liability for fraud or wilful misconduct is void, and Puerto Rico consumer protection law limits how far warranties may be disclaimed in a consumer transaction. Sections 11 and 12 are to be read subject to those limits, and are severable under section 17 to the extent they exceed them.

13. Indemnity

You agree to indemnify and hold harmless the developer from any claim, demand, loss, or expense (including reasonable legal fees) brought by a third party and arising from your use of the app, from content you record in it, or from your breach of these Terms.

14. Stores, updates, and availability

If you obtained Suzztain from Google Play, your use is additionally subject to that store’s terms. These Terms are between you and the developer only; the store operator is not a party to them, is not responsible for the app, and has no obligation to support it.

We may release updates, change features, or add, alter, or remove functionality at any time, and may stop distributing or supporting the app without liability to you.

15. Termination

You may end this agreement at any time by uninstalling the app. Export first if you want to keep your training log.

This licence ends automatically if you breach these Terms. Sections 4, 5, 6, 7, 8, 9, 11, 12, 13, and 16 survive termination.

16. Governing law, venue, and language

These Terms are governed by the laws of the Commonwealth of Puerto Rico, United States, without regard to its conflict of law rules, and by applicable United States federal law.

Any dispute arising from these Terms or your use of the app will be brought exclusively in the Court of First Instance of Puerto Rico, San Juan Judicial Part, or in the United States District Court for the District of Puerto Rico, and you consent to the jurisdiction of those courts.

Nothing in this section prevents you from bringing a complaint before the Puerto Rico Department of Consumer Affairs (Departamento de Asuntos del Consumidor, DACO) where that agency has jurisdiction, or from exercising any right under Puerto Rico consumer protection law that may not be waived in advance.

If you are a consumer resident in the European Economic Area, the United Kingdom, or another jurisdiction whose law gives you the protection of your local courts and mandatory consumer rules, nothing in this section removes those rights.

Language. Spanish and English are both official languages of Puerto Rico. These Terms are issued in English, and the English text governs their interpretation. Any translation is provided for convenience; in the event of inconsistency the English version prevails, except where applicable law requires otherwise.

17. General

These Terms, together with the Suzztain Privacy Policy, are the entire agreement between you and the developer concerning the app.

If any provision is held unenforceable, it is severed and the rest remains in force. Our failure to enforce a provision is not a waiver of it. You may not assign these Terms; we may assign them in connection with a transfer of the app or the business.

18. Changes to these Terms

We may update these Terms as the app changes. The “last updated” date above will be revised, and the current version is posted at https://zerojumpapps.com/legal/suzztain/terms/. Continued use after an update constitutes acceptance of the revised Terms. If you do not accept them, uninstall the app.
