Service availability & third-party infrastructure: Dosth App is built on Google Firebase and depends on the continued availability of Firebase and the other third-party services listed above. We do not control, and are not responsible for, any outage, downtime, data loss, security incident, or discontinuation of service at the infrastructure level of Google Firebase, Google Cloud, or any other third-party provider listed above. In the event of such an incident, our ability to restore service or recover data is limited by that provider's own systems and service commitments, not ours. We do not guarantee uninterrupted or error-free operation of Dosth App.

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.
Specifically, and without limiting the above, you may not: (a) view, extract, copy, screenshot or otherwise reproduce this application's source code, whether via browser developer tools, "view source", cached or offline-stored files, or any other means; (b) reverse-engineer, decompile, disassemble, or attempt to derive the underlying logic, algorithms or structure of the application; (c) use any extracted code, design or content to build, train, or inform a competing or derivative product or service. This applies regardless of whether the application is being used online or offline, and regardless of the technical means by which any part of it happens to be accessible on your device.
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:
Limitation of liability: Dosth App is provided free of charge, "as is" and "as available," without warranties of any kind, express or implied, including any warranty of uninterrupted availability, accuracy, or fitness for a particular purpose. To the maximum extent permitted by applicable law, Dosth App and its developer shall not be liable for any indirect, incidental, special, or consequential damages, or any loss of data, profits, or opportunity, arising from your use of — or inability to use — the app, including but not limited to outages or failures of third-party infrastructure providers (see "Third-Party Services"), disputes between users arising from DosthSell or D Carry arrangements, or reliance on any calculator, AI-generated, or reference content in the app. Nothing in this section limits any liability that cannot be excluded under applicable Indian or Singapore consumer protection law.
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. Posting a D Carry listing requires actively checking a box confirming you have read and agree to this notice.
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.
Chess, Ludo and Word Duel sync results and moves via Firebase for multiplayer and leaderboards; solo vs AI play is not stored. Word Hunt, Dosth 4096, Sudoku, Spelling Scramble and Memory Match run entirely on your device — no scores, progress or gameplay data from these ever reaches Dosth 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. Bank Loan Inquiry is a staff-facing eligibility estimator — customer details entered (name, mobile, income) are never stored on Dosth servers; whenever a message is shared, a record of that inquiry is saved only on the staff member's own device, so it can be found again and exported as a CSV. Your own sign-off text (name/designation) is also saved on your device for convenience across sessions. Receipt Validator reads a photographed bill via AI and checks the maths against the printed total; the photo and extracted items are not stored anywhere by the app, and its "Split this bill" option simply carries those same items into Bill Split — nothing new is stored in the process. Bill Split's optional payment-info field (e.g. your PayNow/PhonePe number) is saved only on your device, never on Dosth servers. None of these tools 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.
Bank Loan Inquiry is a reference tool for bank staff to give customers a preliminary housing-loan eligibility estimate. It does not constitute a loan offer, sanction letter, or commitment by any bank. Final approval is always subject to the bank's complete underwriting process, credit checks and documentation requirements. Dosth App is not affiliated with any specific bank and is not liable for any lending decision, delay or dispute arising from use of this tool. Customer details entered are never transmitted to or stored on Dosth servers. Whenever a message is shared (WhatsApp or copy), Dosth saves a record of that inquiry — name, mobile, DOB, income figures, and the eligibility result — only on the staff member's own device, so it can be found again for follow-up and exported as a CSV for a chosen date range. This record stays on-device only; it is not synced or backed up anywhere by Dosth, and is lost if the app's local storage is cleared.
Receipt Validator uses AI to read a photographed receipt and checks whether the items, tax and discounts add up to the printed total. This is a reference tool only — AI reading can occasionally misread blurry, handwritten or low-light photos, and the app displays exactly what it read so you can verify against the physical receipt. It is not proof of a billing error and should not be the sole basis for a dispute with a merchant. Your receipt photo is sent to Dosth's AI service to be read; the app itself does not save the photo or extracted items anywhere.
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.
