Terms of use
EFFECTIVE 24 AUGUST 2026
These terms are the agreement between you and Waleed Allaudin (“the developer”) covering your use of Patchy Bolus Log. They also serve as the end user licence agreement for the app. By downloading or using the app you accept them. If you do not accept them, do not use the app.
Read this section before you use the app for anything. Patchy Bolus Log is an arithmetic aid and a logbook. It is not a medical device, it does not practise medicine, and it does not give medical advice. It cannot see you, your insulin, your meal, your activity, your illness, or your insulin on board. Every number it produces is the result of arithmetic performed on values you typed in, using settings you configured. Insulin is a high-alert medication and dosing errors can cause severe hypoglycaemia, hospitalisation, or death. Confirm every dose against your own clinical judgement and the guidance of your diabetes care team before you administer anything.
Who may use the app
You may use Patchy Bolus Log only if you are 16 or older and legally able to enter into this agreement. If you are managing diabetes for someone else — a child, or an adult in your care — you are responsible for every dose that results from your use of the app.
You must already have an insulin regimen prescribed by a qualified healthcare professional, including your own carbohydrate ratio, correction factor, and target glucose. The app does not determine those values and will not suggest them. It only applies the ones you enter.
What the app does
Patchy Bolus Log performs two functions:
- It carries out openly stated arithmetic on the carbohydrate amount, glucose reading, and settings you provide, and displays the result.
- It stores the doses you choose to record, on your device, so you can review or export them.
It applies safety limits you can inspect: a maximum bolus cap, a warning when a recent dose may still be active, and a refusal to display any dose at all when the glucose reading you entered is below the low threshold. These limits are conservative aids, not guarantees, and they do not make an incorrect input safe.
What the app does not do
- It does not calculate or track insulin on board.
- It does not read from or write to a continuous glucose monitor, an insulin pump, or Apple Health.
- It does not adjust for exercise, illness, stress, hormones, alcohol, fat and protein content, gastroparesis, or any other physiological factor.
- It does not detect that a setting you entered is wrong for you.
- It does not transmit anything anywhere, and it cannot alert anyone if you are in danger.
Your responsibilities
You are solely responsible for:
- the accuracy of every value you enter, including your carbohydrate ratio, correction factor, target glucose, maximum bolus, and glucose readings;
- verifying each result before acting on it;
- every dose of insulin you administer;
- keeping your settings current with what your healthcare provider has prescribed;
- seeking urgent medical attention when your condition requires it, rather than relying on this or any app.
If a result ever looks wrong to you, it is wrong until you have confirmed otherwise. Do not administer it.
Licence
The developer grants you a personal, limited, non-exclusive, non-transferable, revocable licence to use Patchy Bolus Log on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. The app is licensed to you, not sold.
You may not: copy the app except as permitted by that licence; distribute, rent, lease, lend, sell, or sublicense it; reverse engineer, decompile, or disassemble it except where that restriction is prohibited by applicable law; remove or alter any notice within it; or use it in any manner that violates applicable law.
No warranty
The app is provided “as is” and “as available”, without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement, to the fullest extent permitted by applicable law.
The developer does not warrant that the app will be uninterrupted or error-free, that any calculation will be appropriate for your circumstances, or that defects will be corrected. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.
Limitation of liability
To the fullest extent permitted by applicable law, the developer shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, or goodwill, arising from or related to your use of or inability to use the app — including any harm resulting from an insulin dose administered in connection with its use — whether based in contract, tort, negligence, strict liability, or any other theory, and whether or not the developer has been advised of the possibility of such damages.
To the fullest extent permitted by applicable law, the developer’s total aggregate liability arising out of or relating to the app shall not exceed the amount you paid for it.
Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be excluded or limited. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.
Terms that concern Apple
These terms are between you and the developer only. Apple is not a party to them and is not responsible for the app or its content.
- Maintenance and support. The developer is solely responsible for providing any maintenance and support for the app. Apple has no obligation to furnish any maintenance or support services.
- Warranty. The developer is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the app.
- Product claims. The developer, not Apple, is responsible for addressing any claims relating to the app or your possession and use of it, including product liability claims, any claim that the app fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.
- Intellectual property. If a third party claims that the app or your possession and use of it infringes that third party’s intellectual property rights, the developer, not Apple, is solely responsible for the investigation, defence, settlement, and discharge of that claim.
- Legal compliance. You represent that you are not located in a country subject to a US Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any US Government list of prohibited or restricted parties.
- Third party beneficiary. Apple and Apple’s subsidiaries are third party beneficiaries of these terms, and upon your acceptance of them Apple will have the right, and is deemed to have accepted the right, to enforce them against you as a third party beneficiary.
Termination
This licence is effective until terminated. It terminates automatically if you breach any of these terms, and you may terminate it at any time by deleting the app from your devices. The sections covering warranty, liability, and your responsibilities survive termination.
Changes to the app and to these terms
The app may change over time, and features may be added, altered, or removed. If these terms change, the updated version will be published at this address with a new effective date, and material changes will be noted in the app’s release notes. Continuing to use the app after a change takes effect means you accept the revised terms.
Governing law
These terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable in that province, without regard to conflict of law rules. The courts of Ontario have non-exclusive jurisdiction over any dispute arising from them. Nothing in this section deprives you of the protection of mandatory consumer law in the country where you live.
