Terms of Service

Effective: 2026-06-03 · Last updated: 2026-06-03

These Terms of Service ("Terms") are an agreement between you and TODALABS PTE LTD, a private limited company incorporated in Singapore ("we", "us", "puffphew") governing your use of the puffphew iOS app and any related websites ("Service"). By installing or using puffphew, you agree to these Terms.

If you don't agree, please don't use puffphew.

1. Eligibility

You must be at least 13 years old to use puffphew. If you are under 18, you must have permission from a parent or legal guardian.

puffphew is currently available in the United States, United Kingdom, Canada, and Australia. We may expand later but make no commitment about availability in other regions.

2. Subscription, trial, and billing

puffphew is a paid app. The free trial is the only free experience; there is no permanent free tier.

• Free trial: 14 days, card required. No charge during the trial.
• Plans: Monthly ($4.99) or Yearly ($39.99), prices in US dollars; local pricing applied by Apple where you are.
• Auto-renewal: subscriptions renew automatically at the end of each billing period. Apple charges your Apple ID within 24 hours of period end.
• Managing your subscription: all subscription management — upgrade, downgrade, cancel — happens in Apple's subscription settings. The in-app "Manage subscription" button opens this page directly.
• Cancellation: cancel any time before your trial ends to avoid being charged. Cancel before a renewal date to avoid the next charge. Cancellation takes effect at the end of the current billing period; we do not pro-rate refunds.
• Refund requests: handled by Apple via reportaproblem.apple.com. We cannot issue App Store refunds directly.
• Price changes: if we change pricing, we will notify you in the app at least 30 days in advance. You may cancel before the change takes effect.

3. What puffphew is — and what it is NOT

3.1 What puffphew is

puffphew is a self-tracking journal for facial puffiness patterns. It uses your iPhone's camera and Apple's on-device computer-vision capabilities to take a daily morning measurement, then correlates that measurement against a small set of lifestyle factors you log (or that come from Apple Health). The goal is to help you notice patterns in your own day-to-day variation.

3.2 What puffphew is NOT — Important medical disclaimer

puffphew is not a medical device. puffphew does not diagnose, treat, cure, or prevent any disease or condition. The information puffphew shows is for personal informational purposes only and is not medical advice.

If your face puffiness is sudden, painful, asymmetric (one side only), accompanied by swelling elsewhere, or persists despite obvious explanations, please see a qualified healthcare professional. Puffiness can in rare cases signal a serious underlying issue — puffphew is not equipped to identify those cases and you should not rely on it to do so.

If you have known kidney, thyroid, cardiovascular, allergic, or hormonal conditions, please follow your doctor's guidance regardless of what puffphew shows.

If you are pregnant, recently postpartum, or breastfeeding, your face will fluctuate in ways unrelated to lifestyle factors puffphew tracks. Please factor that in when interpreting your results.

4. How puffphew works — methodology disclosure

We believe you have a right to understand at a high level what we measure and how. Here's the honest summary:

• Measurement: when you take a daily check-in, your iPhone's Vision framework returns a set of face landmark coordinates from the camera image. These coordinates are processed on your device into a small set of geometric ratios that approximate facial puffiness — for example, ratios related to the lower face, the under-eye region, and the cheek/jaw contour.
• Score: the ratios are combined into a single daily "puffiness score" between 0 and 100. The score is meaningful only relative to your own previous scores; comparing scores between two different people is not meaningful and we do not surface such comparisons.
• Baseline: your first morning capture sets an initial reference point. Once you have enough captures, the reference recalibrates to the typical value among your earliest mornings. Your daily deviation is expressed as a percentage relative to this personal reference.
• Correlation: we run a standard statistical analysis on your captures + lifestyle log to estimate which factors (sleep, alcohol, sodium, hydration, workouts, cycle phase) are most associated with higher or lower puffiness scores in your own data. We surface a correlation only when there are enough data points and the relationship is clear enough; we explicitly avoid presenting weak or unstable correlations.
• Forecast: the day's forecast is a simple aggregation of the per-factor effects we have already established from your own correlation analysis. Where you have very little data, we fall back to general population priors and label the forecast accordingly.
• All computation runs on your device. None of the measurements, scores, or correlations are computed on a server, and none are transmitted off your device.

We deliberately do not publish: the exact ratio formulas, the specific statistical thresholds we use for significance, the data-window lengths, or our weighting between factors. These are part of how puffphew works as a product. If you have a genuine research interest, contact us.

5. Your content and our intellectual property

• You own your captures and logs. They never leave your device under our operation. We claim no rights to them.
• We own the app. puffphew, the puffphew brand, our website, the software we write, our user interface designs, and our methodology described in §4 are owned by TODALABS PTE LTD and protected by copyright, trademark, and trade-secret law. You may use puffphew under these Terms but you may not copy, reverse-engineer, decompile, scrape, or build a competing product using our app's outputs.
• Feedback you send us (e.g., a bug report, a feature suggestion via email) may be used by us freely without obligation. We won't publish your name without permission.

6. Acceptable use

You agree not to:

• use puffphew for any unlawful purpose;
• attempt to gain unauthorized access to puffphew's app sandbox or our subprocessor accounts;
• reverse-engineer the app or extract our proprietary methodology beyond what §4 discloses;
• use puffphew to harass, defame, or harm anyone — including yourself or others depicted in your photos;
• circumvent the subscription paywall.

7. Service availability; changes

We aim to keep puffphew working but make no uptime guarantee. We may update the app, change features, or in rare cases discontinue puffphew entirely. If we discontinue, we will notify active subscribers at least 30 days in advance via the app and via Apple's subscription mechanism, and you will not be charged for any period after the discontinuation date.

We may modify these Terms by updating the "Last updated" date and notifying you in the app. If a change materially reduces your rights, we will notify you at least 30 days in advance.

8. Disclaimer of warranties

puffphew is provided "as is" and "as available" without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or that the app will be uninterrupted or error-free.

To the maximum extent permitted by law, we disclaim all liability for any inaccuracy in puffphew's measurements, scores, correlations, or forecasts. Puffphew is a self-tracking tool, not an instrument of medical or clinical precision.

9. Limitation of liability

To the maximum extent permitted by law, neither TODALABS PTE LTD nor its directors, officers, employees, or subprocessors will be liable for any indirect, incidental, consequential, special, exemplary, or punitive damages, or for any loss of profits, revenues, data, or goodwill, arising out of or related to your use of puffphew.

Our total liability for any claim arising out of or related to puffphew, regardless of legal theory, will not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) US $50.

Some jurisdictions do not allow these limitations; in those jurisdictions our liability is limited to the smallest amount allowed by applicable law.

10. Termination

You may terminate this agreement at any time by cancelling your subscription and uninstalling puffphew. Use Settings → "Delete all data" first if you want to ensure no residual files remain on your device.

We may terminate or suspend your access if you breach these Terms, if required by law, or if continued service becomes unviable. We will refund any unused prepaid subscription period if we terminate for reasons other than your breach.

Sections 4–9 and 11–13 survive termination.

11. Governing law and disputes

These Terms are governed by the laws of the Republic of Singapore, without regard to its conflict-of-laws principles. Any dispute arising out of or in connection with these Terms — including any question of existence, validity, or termination — that cannot first be resolved by good-faith negotiation will be referred to and finally resolved by arbitration administered by the Singapore International Arbitration Centre (SIAC) under the SIAC Rules in force at the time, seated in Singapore, in the English language, before a single arbitrator. The award shall be final and binding.

Nothing in this section prevents either party from seeking urgent injunctive or equitable relief from a court of competent jurisdiction.

If you are a consumer resident in the European Union, United Kingdom, or any jurisdiction whose consumer-protection laws would otherwise apply, this section does not deprive you of mandatory consumer protections under your local law, and you may bring claims locally where required by such law.

12. Apple-specific terms

Because puffphew is distributed through the Apple App Store:

• These Terms are between you and TODALABS PTE LTD, not Apple. Apple is not responsible for puffphew or for any claims arising from it.
• Apple has no obligation to provide maintenance or support for puffphew.
• If puffphew fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the subscription price (if any) per its standard policy. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to puffphew.
• Apple is a third-party beneficiary of these Terms and may enforce them against you.

13. Miscellaneous

• Entire agreement. These Terms plus our Privacy Policy are the entire agreement between you and us about puffphew, replacing any earlier discussions or marketing claims.
• No waiver. Our failure to enforce a provision is not a waiver of our right to enforce it later.
• Severability. If any provision is held unenforceable, the rest remain in effect.
• Assignment. You may not assign your rights under these Terms. We may assign ours to a successor entity (e.g., in an acquisition).
• Contact. Questions, notices, or legal communications: michele@todalabs.io or by post to TODALABS PTE LTD at our registered address on file with the Singapore Accounting and Corporate Regulatory Authority (ACRA).
