terms. the boring shit.
last updated: may 1, 2026
use the app to look at ur face. don't be a dick. we're not doctors. if shit breaks we owe u nothing. india law applies. use = u agree.
what u're agreeing to
by using tinkskin (the website at tinkskin.in, the scans, the routine, all of it) u agree to these terms. don't agree? close the tab. that's it.
these terms are between u and helldock (the solo dev who built this). references to "we" / "us" mean me. references to "u" / "user" mean u, the person reading this on ur phone at 3am.
what this iscosmetic AI, not a doctor
- tinkskin is a cosmetic skin analysis tool. u upload pics, an AI vision model takes a look, u get a score + a routine of products with clinical evidence behind the ingredients.
- this is not a medical diagnosis. nothing on this site is a substitute for a real board-certified dermatologist. if something on ur skin is changing, bleeding, painful, or just sus — go see a doctor irl. period.
- the AI can be wrong. we're upfront about that. don't make medical decisions off vibes from this app.
age + jurisdiction
- u must be at least 13 to use tinkskin. if u're under 16 (or under whatever ur country's "digital consent" age is — 16 in EU, 13 in US under COPPA, etc.), u need a parent or guardian's say-so.
- tinkskin is operated from india. it's available globally but if ur local laws make this kind of cosmetic AI service illegal where u live, don't use it. that's on u to know.
ur photos stay urs
- u own everything u upload — ur photos, ur scan results, ur diary entries, all of it. always.
- u grant us a tiny temporary license to forward ur photo to the AI vision model so it can analyze ur skin. that's it. no other use, no marketing, no training data. see privacy policy for the full data flow.
- if u opt into google drive backup, photos go to ur drive. we never hold a copy.
- u can wipe everything off ur device anytime via the "wipe" button on the privacy page.
shit u can't do
- don't upload pics that aren't urs without that person's consent. don't upload kids who can't consent. don't upload anything illegal.
- don't try to break the app — no scraping, no DDoS, no trying to extract our prompts or training data, no abusing the API endpoints.
- don't reverse-engineer or rebrand and resell this. it's MIT-spirit but the brand + my time aren't.
- don't use tinkskin to harass, dox, or harm anyone. obvious shit.
- don't use scans or recommendations to give medical advice to other people. u're not a doctor either.
break these and we can pull ur access. no notice, no refund (it's free anyway).
the AIaccuracy disclaimer (real talk)
the AI vision models we use (Qwen 2.5 VL, Llama 3.2 Vision, GPT-4o mini, etc.) are good but not perfect. they hallucinate. they miss stuff. they sometimes call a freckle a melanoma and vice versa. we tune the prompts to be cautious but we can't guarantee accuracy.
treat scan results as a starting point, not a verdict. compare with how ur skin actually feels. and again — anything serious or weird, see a derm irl.
amazon linksaffiliate disclosure
product links go to amazon with affiliate tags. tinkskin earns a small commission on qualifying purchases at no extra cost to u. recommendations are picked on clinical evidence + ur scan results — affiliate cut never moves the rankings. if u'd rather not give us a cut, just google the product name yourself.
tipsdonations are gifts, not sales
tips u send via the donate page (coindrop) are gifts. not subscriptions, not pre-payments for features, not refundable. nothing about ur experience changes whether u tip or not. no perks unlock, nothing held hostage. ur scan history, recommendations, and routine are identical free vs. paid.
when shit breaksservice availability
- tinkskin is offered as-is. it might go down, run slow, hit AI rate limits, or break in weird ways. it's a free app run by one dev — i can't guarantee 99.9% uptime.
- we may change, pause, or shut down features at any time without notice. (we'll try to give a heads up but not promised.)
- data on ur device persists locally (localStorage + IndexedDB). data on our server (if u sign in with google) persists until u delete ur account or we shut the service down. if we ever shut down, we'll give 30 days notice + a way to export ur data.
Disclaimer of warranties
tinkskin is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, accuracy, non-infringement, or that the service will be uninterrupted or error-free. The AI-generated analysis is not medical advice and may contain inaccuracies. We do not warrant that the service will meet your requirements or that any errors will be corrected.
Limitation of liability
To the maximum extent permitted by law, tinkskin (helldock) shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising from your use of or inability to use the service — including but not limited to reliance on AI-generated skin analysis, ingredient recommendations, or product links. Our total cumulative liability for any claim arising out of or relating to these terms or the service shall not exceed the amount you have paid us in the past twelve months, which for a free service is zero (₹0 / $0).
Some jurisdictions don't allow the exclusion of certain warranties or limitation of liability, so some of the above may not apply to you. In those cases, our liability is limited to the maximum extent permitted by applicable law.
law + where we'd fight about this
these terms are governed by the laws of india. any disputes go to the courts of india. if there's a conflict between these terms and ur local consumer-protection laws, ur local laws win to the extent legally required.
changesterms can change
if we update these terms in a meaningful way, we'll bump the "last updated" date at the top + show a banner on the home page for a couple weeks. continuing to use tinkskin after the change means u accept the new terms. if u don't agree, stop using it and (if u're signed in) wipe ur data via the privacy page.
