The short version.

Last updated: 9 September 2026

You may use our apps for your own personal use. We do our best to keep them working well, but they're provided as they are. Subscriptions renew until you cancel, and you cancel in the App Store — not with us.

1. Who these terms are with

These Terms of Use ("Terms") are an agreement between you and Sirek Apps ("we", "us"), a software studio based in Gdańsk, Poland. They apply to every iOS app we publish and to this website.

By downloading or using an app, you accept these Terms. If you don't agree with them, please don't use the app.

2. Your licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to use our apps on devices you own or control, in line with the App Store Terms of Service.

You may not copy, sell, rent, sublicense, reverse-engineer, decompile, or attempt to extract the source code of our apps, except where that restriction is prohibited by applicable law.

3. Your content

Anything you enter into an app is yours. We claim no ownership over it, and — as set out in our Privacy Policy — it stays on your device and in your own iCloud account. You are responsible for your content and for keeping your own backups.

4. Subscriptions & purchases

Some features require a paid subscription or a one-time purchase. All payments are processed by Apple through In-App Purchase; we never handle your payment details.

Prices are shown in the app before you buy, in your local currency.
Where a free trial is offered, any unused portion is forfeited if you buy a subscription during the trial.
Subscriptions renew automatically at the end of each period unless auto-renew is turned off at least 24 hours beforehand.
Your account is charged for renewal within 24 hours of the end of the current period.
You can manage or cancel a subscription in your App Store account settings at any time. Deleting the app does not cancel a subscription.
A lifetime purchase, where offered, is a one-time payment and does not renew.

5. Refunds

Purchases are handled by Apple, so refunds are handled by Apple too, under their policies. You can request one at reportaproblem.apple.com. We cannot issue refunds directly. If you are an EU consumer, your statutory rights are unaffected.

6. Acceptable use

Please don't use our apps unlawfully, don't interfere with or disrupt them, and don't try to gain unauthorised access to any part of them or to any related systems.

7. Not medical advice

Some of our apps help you record health, nutrition or fitness information. They are tools for tracking, not medical devices, and nothing in them is medical or dietary advice. Always speak to a qualified professional before making decisions about your health or diet. You use them at your own discretion.

8. Calculations and measurements

Some of our apps work out measurements for trade and construction work — bend marks for conduit, conduit and box fill, and similar figures. They are calculation aids. They are not a substitute for your own training, your own judgement, or the codes and standards that apply to your job.

Every figure depends on the values you enter and on the tool actually in your hands. Take-up, bend radius and springback differ between makers, between models of the same maker, between materials and with temperature, and published figures are approximations that the app expects you to correct. Field multipliers taught in the trade are deliberately rounded and are not exact trigonometry.

Check every figure before you cut, bend or install anything. Measure the result. Compliance with the National Electrical Code, any local amendment, and any inspection is your responsibility and not ours.

Where an app measures an angle using the device's motion sensors, it reports what the sensors report. A phone is not a calibrated measuring instrument; readings depend on the hardware, on how the device is placed and on what it is resting against.

To the fullest extent permitted by law, we are not liable for wasted or damaged material, rework, delay, cost, lost work, property damage, failed inspection or code violation, or any injury arising from reliance on a figure produced by one of our apps.

9. AI-generated opinions

Some of our apps take text you provide and return an opinion about it — a verdict, scores, a reading of tone, and suggested rewrites. These are produced automatically, in part by third-party AI models. They are entertainment and a second opinion. They are not advice of any kind, they are not a prediction of what another person will do, and they are frequently wrong.

You decide what to send. Whether you send a message, what you send, and everything that follows from sending it are your responsibility and not ours. A rewrite an app suggests is a draft for you to read and judge before it leaves your phone.

We do not warrant that any output is accurate, complete, appropriate, suitable for any purpose, or free of content you may find wrong, unfair or offensive. Output can vary between runs on identical input. Automated safety filtering is best-effort and will not catch everything.

You are responsible for the text you put into an app. Do not paste anything you are not entitled to share, and do not paste other people's personal, confidential or sensitive information. Where an app sends text to a model provider to be read, you confirm you have the right to do so.

These apps are not a crisis service, a counselling service, a legal service, or a substitute for talking to a person. If a message concerns anyone's safety, contact a qualified professional or your local emergency or crisis service.

To the fullest extent permitted by law, we accept no liability for any consequence of a message you send or do not send, for any reliance on an opinion, score or rewrite produced by an app, or for any content returned by a model provider — including damage to a relationship, reputation, employment or any other loss.

10. Third-party services

Our apps rely on services we don't control — Apple's App Store, iCloud and Apple Health, RevenueCat for subscription management, AI model providers such as OpenAI where an app returns a generated opinion, and, where an app looks something up, public third-party databases such as Open Food Facts. We aren't responsible for the accuracy, availability or content of third-party services. Data returned from a community-maintained database may be incomplete or wrong.

11. Availability & changes

We may update, change, or discontinue an app or any of its features. We'll try to avoid disruption where we reasonably can, but we can't guarantee an app will always be available or supported indefinitely.

12. Disclaimer & liability

Our apps are provided "as is" and "as available", without warranties of any kind to the extent permitted by law. We do not warrant that they will be uninterrupted, error-free, or that any data will be preserved.

To the fullest extent permitted by law, our total liability arising out of or relating to an app is limited to the amount you paid us for it in the twelve months before the claim. Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited. If you are a consumer, your mandatory statutory rights are unaffected.

13. Changes to these Terms

We may revise these Terms as our apps evolve. We'll update the "last updated" date above, and continued use after a change means you accept the revised Terms.

14. Governing law

These Terms are governed by the laws of Poland. If you are a consumer, you benefit from any mandatory provisions of the law of the country in which you reside, and you may bring proceedings in your local courts.
