Dosth App is officially registered with the Copyright Office, Government of India under the Copyright Act, 1957.
All source code, UI design, written content, graphic assets, animations and web pages of Dosth App are protected under copyright law. Unauthorised copying, reproduction or distribution is prohibited and may result in legal action.
By using Dosth App you agree to use it lawfully and not to misuse AI features, post fraudulent listings, or attempt to reverse-engineer the app.
Dosth Drop & file transfer: By using Dosth Drop you additionally agree:
Governed by the laws of India. Disputes subject to Indian courts. Users in India retain rights under Consumer Protection Act 2019 and DPDP Act 2023. Users in Singapore retain rights under PDPA 2012 and Consumer Protection (Fair Trading) Act.
Dosth App does not hold, transfer or process S$ funds. All transactions are in ₹ INR between members directly. Dosth is not regulated by MAS and does not require a Payment Services Licence as it does not provide payment services.
D Carry listings are community arrangements between members. Dosth App is an intermediary only and is not responsible for:
Singapore Customs personal duty-free allowance: up to S$400 (air/sea). Always declare items. All customs compliance is the sole responsibility of the carrier and requester.
Dosth App does not show advertisements. There is no Google AdMob, AdSense, or other ad-network integration in the app or on the website. No device advertising identifier is collected. The app is sustained through voluntary community contributions (see "Voluntary Contributions" below). If advertising is introduced in the future, this section and the FAQ will be updated in advance and existing users will be notified in-app — and Dosth App will not control specific ad content if ads are introduced.
Dosth App's core features are committed to remain free for all users. As the app evolves, optional premium features may be introduced (such as an ad-free experience, advanced analytics, unlimited AI queries, or printable certificates). Any premium offering will be clearly marked as optional and will not restrict access to features available in the free tier at the time of your account creation. Pricing and terms for premium features, if and when introduced, will be communicated transparently in advance and will require explicit opt-in. We will never convert an existing free feature into a paid-only feature for existing users.
Dosth Games (Chess and future games) store only your aggregate result statistics (wins, losses, draws, games played) and your Dosth Tag for the global leaderboard. Multiplayer game move history is stored in Firebase for real-time sync and deleted when you delete your account. Solo vs AI games are not stored on servers.
Games are for entertainment only. No financial transactions are involved. You control your leaderboard visibility — toggle it off at any time in Rankings.
All Study data (exam timetables, study plans, preferences) is stored exclusively on your device using browser localStorage or AsyncStorage. Nothing is uploaded to Dosth servers. Clearing your browser data or uninstalling the app removes this data.
Home Vault is a personal home inventory tracker. All data — including item names, brands, model numbers, serial numbers, purchase dates, purchase prices, warranty months, service contacts, and notes — is stored exclusively on your device using AsyncStorage (mobile) or localStorage (web). Dosth servers never receive or process this information. There is no cloud sync, no backup, and no cross-device sharing. If you uninstall Dosth or clear app data, the inventory is permanently lost.
QR Maker generates QR codes locally on your device using an embedded pure-JavaScript QR encoder. Inputs (vCard contact details, UPI ID/amount/note, WiFi SSID/password, links, plain text) are converted to a QR matrix and rendered as SVG on your device. Nothing is sent to any Dosth server. Saved drafts (so you don't re-enter your name, UPI ID, or WiFi credentials each time) are stored only on your device via AsyncStorage/localStorage. Once you share a generated QR code as an image, anyone who scans it can decode the embedded data — share carefully, especially WiFi passwords.
How it works. Dosth Drop is a peer-to-peer file transfer service. Files are sent directly between the sender's and receiver's devices — they never pass through, are stored on, or are accessible to Dosth servers.
What we store: Nothing. Dosth has no server-side component for Dosth Drop. We cannot recover, inspect, revoke, or replay transfers.
What is briefly visible to third parties: PeerJS Cloud sees the 6-digit code and the public IP addresses of both devices during the ~5-second handshake — never file content. Google STUN servers see IP addresses only.
Honest limits of our encryption: Dosth Drop encrypts files in transit between the two devices (DTLS). However, encryption does not protect the devices themselves. If you are on a monitored device (work laptop, school laptop), endpoint monitoring software on that device may see file content before it is encrypted for transit. Additionally, both sender and receiver can see each other's public IP addresses during the transfer — this is how WebRTC works on the open internet.
Your responsibilities: You are responsible for what you transfer. Dosth Drop must not be used to send illegal content, copyrighted material without rights, malware, or non-consensual intimate images. We cannot enforce this technically (we do not see file content), but such use violates our Terms of Use.
Scanned documents and converted files are processed locally in your browser and are not uploaded to Dosth servers. Passport photo background removal uses the remove.bg API — images are sent to remove.bg for processing under their privacy policy (remove.bg/privacy). Dosth does not retain passport photos.
Dosth App is an intermediary platform only. We do not own, verify or guarantee listed items, delivery, or item condition. All transactions are solely between buyer and seller.
Gold Calculator shows price comparisons between Singapore and India for reference only — it does not recommend where to buy gold. Loan Calculator provides EMI estimates using standard formulas. Neither tool constitutes financial, investment or banking advice. Always confirm with your bank or jeweller before transacting. Check customs allowances before travel.
Important — Legal nature: Voluntary contributions to Dosth App are not charitable donations within the meaning of Section 80G of the Income Tax Act, 1961. Dosth App is not a registered charitable trust, Section 8 company, or 80G-approved institution. Contributions are voluntary support payments to the developer and are not tax-deductible. The developer declares contributions received as business income for income tax purposes. Do not treat your contribution as a donation for tax-deduction purposes — no 80G receipt will be issued, and no deduction can be claimed.
Contributions via "Support the Team" are voluntary, non-refundable, and do not grant additional privileges, features, or status. They are direct UPI payments from contributor to the developer's bank account; the contribution record submitted within the app is a self-declared record of payment used to populate the public contributions feed within the app.
Verification: Each contribution is initially marked "pending" and reviewed by the team against the UPI transaction record provided. Verified contributions are marked "verified". Unverified or fraudulent submissions may be removed at the team's discretion.
Retention: Contribution records (including dostuTag, amount, message, transaction ID, and timestamp) are retained in Firestore for as long as the public contributions feed remains active, or until you request deletion. Account-linked uid is retained for fraud prevention and is removed when you delete your Dosth account.
Right to deletion: You may request removal of your contribution from the public feed at any time by emailing support@dostu.app from your account's registered email. Deletion is typically completed within 30 days. Note: deletion removes the public feed entry; bank-level UPI transaction records held by your bank are governed by your bank's policies, not Dosth.
Minor protection (DPDP Act 2023 § 10): Users must be 18 or older to contribute. The Support the Team flow requires a logged-in Dosth account; account creation already requires confirmation of being 18+. Contributions from accounts later identified as belonging to a minor will be refunded where the UPI transaction can be reversed and the record will be removed from the feed.
Community ideas board: Submitted feature ideas (text up to 280 characters) and upvotes are stored in Firestore and publicly visible to all logged-in users along with your dostuTag. Same retention and deletion rules apply as for contribution records.
Dosth App facilitates connections between community members for carrying items between India and Singapore. We do not verify items, carriers, requesters or WhatsApp numbers. All arrangements, payments and customs compliance are solely the responsibility of the parties involved. Dosth App is not liable for any loss, damage, seizure or dispute arising from D Carry arrangements.
This tool shows price differences between Singapore and India for personal reference. It does not recommend where to buy gold. Gold prices fluctuate continuously. Estimates are based on inputs you provide and international spot rates. Not investment advice. Always confirm final price with your jeweller. Check customs allowances before travel. Dosth App is not liable for any loss arising from gold price estimates.
EMI calculations are estimates using standard reducing-balance formula. Actual EMI may differ based on your bank's specific terms, processing fees and insurance. Not financial or mortgage advice. Consult your bank or a licensed financial advisor before taking any loan.
AI-generated crop, weather and farming advice is general information only. Not professional agricultural advice. Always consult qualified agricultural experts for farming decisions.
Health is a manual vitals tracker for personal awareness only. Not a medical device. Do not make medical decisions based on data in Health. Always consult a qualified healthcare professional.
You are solely responsible for political content you generate and share. Dosth App does not endorse any political party, candidate or ideology. Content must comply with Election Commission of India guidelines and applicable laws.
All AI features generate content AS-IS with no guarantee of accuracy. Always review AI output before using for any important decision.
